kandi X-RAY | money Summary
PHP library to make working with money safer, easier, and fun!. "If I had a dime for every time I've seen someone use FLOAT to store currency, I'd have $999.997634" -- Bill Karwin. In short: You shouldn't represent monetary values by a float. Wherever you need to represent money, use this Money value object. Since version 3.0 this library uses strings internally in order to support unlimited integers. The documentation is available at

QUESTION
I have a union, defined like so:
...ANSWER
Answered 2022-Mar-18 at 19:33If you are using pre C++11 compiler then:
Unions cannot contain a non-static data member with a non-trivial special member function (copy constructor, copy-assignment operator, or destructor).
and std::string has non-trivial all of the above functions.
If you are using compiler which supports C++11:
If a union contains a non-static data member with a non-trivial special member function (copy/move constructor, copy/move assignment, or destructor), that function is deleted by default in the union and needs to be defined explicitly by the programmer.
If a union contains a non-static data member with a non-trivial default constructor, the default constructor of the union is deleted by default unless a variant member of the union has a default member initializer.
This basically means that you don't have any of the union constructors and you need to define copy or move constructor yourself for the following line to work:
QUESTION
I am making a finance management application. I have a database containing all the places the user has his money which includes banks. Here is how the table is structured..
...ANSWER
Answered 2022-Mar-04 at 17:55Advice/opinion
A database is for persistent storage of numbers and text.
An app is for computing and deciding things.
That is, the complex business logic you describe may be more appropriately encoded in Java (or other app language). Meanwhile, the breakpoints, etc for interest rates should be stored in the database.
Phrased differently: "Business logic" belongs in the app, not the database. (There is, of course, a gray lines between them. For example, SQL is excellent at summing up all the data in a table; so, I would do that in SQL, not Java.)
Decimal
Banks have picky rules that may not be the same as what DECIMAL
or DOUBLE
provide -- in Java or MySQL or _any other computer language. Be careful of the rules that may be required. In particular, DECIMAL(10, 4)
is unlikely to be adequate in your application. On the other hand, apy DECIMAL(4, 2)
may be adequate if that is what is presented to the customer. But, again, beware of rounding rules when generating that number. You may be forced to enter that number manually.
Be aware of the difference in rounding characteristics between DECIMAL
and DOUBLE
.
Answer
If you choose to implement an algorithm in the database, then see CREATE STORED PROCEDURE
and CREATE FUNCTION
.
Stored Procs can be used to encapsulate a set of SQL statements. It can receive and send strings and numbers, but not arrays. It is capable of reading tables (hence "arrays" of a sort.)
Functions can be called anywhere an expression can occur. It can receive some numbers/strings and produce one number or string.
Array
I'm not clear on what is needed, but I envision a table of a few rows or a few dozen rows with each row saying "for values up to $xxx, use y.yy% interest rate".
Stored Procs have "cursors" and "loops" but they are clumsy; the app language is likely to have better code.
QUESTION
I looked at the standard documentation that I would expect to capture my need (Apache Arrow and Pandas), and I could not seem to figure it out.
I know Python best, so I would like to use Python, but it is not a strict requirement.
ProblemI need to move Parquet files from one location (a URL) to another (an Azure storage account, in this case using the Azure machine learning platform, but this is irrelevant to my problem).
These files are too large to simply perform pd.read_parquet("https://my-file-location.parquet")
, since this reads the whole thing into an object.
I thought that there must be a simple way to create a file object and stream that object line by line -- or maybe column chunk by column chunk. Something like
...ANSWER
Answered 2021-Aug-24 at 06:21This is possible but takes a little bit of work because in addition to being columnar Parquet also requires a schema.
The rough workflow is:
Open a parquet file for reading.
Then use iter_batches to read back chunks of rows incrementally (you can also pass specific columns you want to read from the file to save IO/CPU).
You can then transform each
pa.RecordBatch
fromiter_batches
further. Once you are done transforming the first batch you can get its schema and create a new ParquetWriter.For each transformed batch call write_table. You have to first convert it to a
pa.Table
.Close the files.
Parquet requires random access, so it can't be streamed easily from a URI (pyarrow should support it if you opened the file via HTTP FSSpec) but I think you might get blocked on writes.
QUESTION
I am working on a donation app. In this app, There was a feature that sends an equal amount of donation money to every employee of the organization now they want to change this feature by sending a customized amount of donation to all or some of the employees.
I have worked on it: Now I am using a for loop which iterates over the list of employees id and gives the amount to each id. But What I want is to pass an object in a for loop
, where the object has an id
from list of ids
and the amount
received from payload
. I want to keep that id
with his specific amount
locked in an object
Here is my code now:
ANSWER
Answered 2022-Feb-17 at 07:57One approach I can think of is, you can customize the amount of donation of some/all employees and distribute the rest to others equally. For example:
Implementation: (AJAX + DRF)I want to donate $10,000 to 10 employees. Originally, each of them would receive $1000. But I want Employee-A and Employee-B to receive $1200 and $1300 respectively. Now I am left with $8500 and 8 employees. So, each 8 of them will receive $1062.5.
You have to add some input fields in your front-end. This is to customize which employee should receive how much donation. You should keep track of the employeeId
as you will need it later while sending the payload to your server.
Create a JSON list (from your form) like this and pass it to the API call.

I'm hoping to get some insight into a issue I'm facing using QDoubleValidator, I have created a widget to collect some information, and would like to have some fields validated as Double values, I have done so here:
...ANSWER
Answered 2022-Jan-12 at 07:46Maybe your validator range (0.0 to 5.0) is too narrow. If a newly calculated value falls outside the range, the validator state won't be QValidator::Acceptable
anymore, and, as a side effect, the line edit will no longer emit the editingFinished signal.
You could try keeping the validator's top()
to its default (infinity) value, maybe using the other constructor and using setters to set decimals and range bottom:
QUESTION
I am making a program that allows you gamble and it creates an object of the player with attributes like current money, how many wins/losses the player has etc..
I am currently able to have this working and the information is saved while the program is running, however I want to implement a feature that allows me to save this user information in a json and then next time the program is run, check that json to see if the name entered by the player matches any value for 'name' in the json and pull their profile from when they last played.
Currently I am learning how to read/write json data and I am able to get data saved to a json, but I'm unable to save it in the format that I want and retrieve it later and convert the data back into my object with attributes.. Specifically I can save the user like this:

QUESTION
I'm trying to understand histomorphisms from this blog on recursion schemes. I'm facing a problem when I'm running the example to solve the change making problem as mentioned in the blog.
Change making problem takes the denominations for a currency and tries to find the minimum number of coins required to create a given sum of money. The code below is taken from the blog and should compute the answer.
...ANSWER
Answered 2021-Oct-20 at 12:38I see two problems with this program. One of them I know how to fix, but the other apparently requires more knowledge of recursion schemes than I have.
The one I can fix is that it's looking up the wrong values in its cache. When given = 10
, of course validCoins = [10,5,1]
, and so we find (zeroes, toProcess) = ([0], [5,9])
. So far so good: we can give a dime directly, or give a nickel and then make change for the remaining five cents, or we can give a penny and change the remaining nine cents. But then when we write lookup 9 attr
, we're saying "look 9 steps in history to when curr = 1
", where what we meant was "look 1 step into history to when curr = 9
". As a result we drastically undercount in pretty much all cases: even change 100
is only 16, while a Google search claims the right result is 292 (I haven't verified this today by implementing it myself).
There are a few equivalent ways to fix this; the smallest diff would be to replace
QUESTION
I switched from the deprecated GDPR Consent Library to the new User Messaging Platform, and used the code as stated in the documentation.
I noticed that when the user clicks on Manage Options then Confirm choices, ads will stop displaying altogether (Ad failed to load, no ad config), and I can't find anyway to check if the user didn't consent to the use of personal data.
This is problematic as my app relies purely on ads, and I will be losing money if ads don't show up, so I want to make it mandatory for users to consent to the use of their personal data, otherwise the app should be unusable.
I have made a test project on Github so everyone can test this behavior. If you are not using an emulator, then you need to change the "TEST_DEVICE_ID" to yours.
How can I achieve this?
...ANSWER
Answered 2021-Nov-02 at 17:50I found a workaround for this, but this is no final official solution.
It seems that if a user consented to Personalized ads, a string in SharedPreferences
, which key is IABTCF_VendorConsents, will contain ones and zeros corresponding to some vendors (I think). If he didn't consent, this string will be equal to 0.
