decimal.js | An arbitrary-precision Decimal type for JavaScript | Math library

Hello my fellow developers!

So I've been working on this app for a while now. I like to be up to date with the frameworks I use, so I regularly update when the frameworks release a new version. i.e. Angular 9 > 10. Angular 10 > 11.

So I just recently updated to Angular 11 and updated my nestjs and nx. And now when I try to serve my frontend app, Ivy seems to complain a lot.. but a.. lot... about modules that are not used in the frontend app.

i am working with money values here. I have an unknown amount of money of a unkown currency (compiletime unknown ofc). I have multiple targets to divide that amout to.

One example:

Amount is $3.02 and i will divide with three friends so each will get $1 leaving 2 cents to spare. Now as the amount has to be correct at the end i split up the remainder between the parties untill all cents to spare are gone.

Note that the same has to work for yapanese yen. They don't have cents. There it would be for example 32 divided by 3 equals 10 each and 2 to spare.

In the following code cents is a decimal.js value with the remainder of the split mentioned above (e.g "0.02" or just "2").

i have strings that represents money. E.g 29.00 or 29.10 or 29.13 the currency however can change and does not necessarily lead to a value that has two decimal places by default (Yen for example does not have decimal places at all)

Now, i use Decimal.js to execute calculations with these values

For example i am multiplying with a percentage

How to write Excel CEILING(number, significance) function in JavaScript or in decimal.js

CEILING(10,3) = 12 round up to nearest 3

CEILING(36,7) = 42 round up to nearest 7

CEILING(560,100) = 600 round up to nearest 100

CEILING(6.36,0.05) = 6.40 round up to nearest 0.05

Simple maths with JS gets wrong when using decimals.

I have an Express app which returns big decimal numbers (their textual representations) in response.

I'm trying to set up a data pipeline between Bloomberg and Python. I have a Bloomberg terminal, a Windows 64-bit machine, Python 3.7.4 and a Sublime Text environment up and working. My goal is to install the XBBG package: https://pypi.org/project/xbbg/.

I've followed the steps on https://pypi.org/project/xbbg/ and I have installed:

• Bloomberg C++ SDK version 3.12.1 or higher
• Bloomberg Open API (need to install manually as shown below)
• pdblp - pandas wrapper for Bloomberg Open API
• numpy, pandas, ruamel.yaml

However the pip install pyarrow installation does not work (see traceback below), even when I tried earlier versions of pyarrow.

I would like to share TS classes or interfaces between a React + TS frontend and node + TS backend. The problem is that TS types are stripped away in compile time, so I cannot use them when I want to convert a class instance into a JSON.

I was wondering if there are any solutions with which I could describe my object in a static file, generate the TS classes, and use this file for data hydration and dehydration as well. Some properties are moment.js objects and Decimal.js objects. I am looking for a solution where the conversion can be done based on the static descriptor, I don't need to write it for every property manually.

The dehydrated format is used in HTTP request plus it's stored in the DB (Firebase Firestore) and accessed directly by the frontend for reading.

I am using decimal.js light in my angular application.

I want to get integer and fraction part by using Decimal.js.

Eg. input: 123.45 integer: 123 decimal: 45
