kandi X-RAY | multiplication Summary

multiplication is a C++ library typically used in Artificial Intelligence, Machine Learning, Example Codes applications. multiplication has no bugs, it has no vulnerabilities and it has low support. You can download it from GitHub.

Here is very basic implementation of naive multiplication (which takes ) and Karatsuba algorithm (which takes ). Now, it is using vectors for storing numbers with base 10. Further improvments should be to change base of all numbers which are stored in input vectors.

Javascript const variable is changing after multiplying with another variable

Asked 2021-Jun-15 at 19:09

I am trying to create a shopping cart in JavaScript. When I click on the button, the price of item should increase according to the number of times I have clicked on the button. I've tried the below code but it's not working. The problem is that after clicking few times the multiplication goes like this: suppose initial price =49
49 x 1
49 x 2
94 x 3
282 x 4 (it should be 49 x 4); I have modified the code,it works fine in console.log() but gives different result if I assign the variable newPrice to document.getElementById().innerHTML

...

ANSWER

Answered 2021-Jun-15 at 12:34

I think this const newprice = document.getElementById("discount").innerHTML *=counter;

should be const newprice = document.getElementById("discount").innerHTML +=counter;

note the + and not the * before the =counter. the plus is adding the star is multiplying.

QUESTION

Why is an in-place integer operation like a *= b slower than a = a * b?

Asked 2021-Jun-13 at 11:37

I know integers are immutable so the computed values do not modify the original integers. Therefore the in-place operations should do the same as the simple operations, 1. compute the value and 2. reassign the value back to the variable. But why are the in-place operations slower than the simple ones?

...

ANSWER

Answered 2021-Jun-13 at 11:37

There may be a problem in that experiment: a single for-loop with 100 iterations and only containing an assignment statement like a=a+1 or a+=1 normally will not take that long to run (more than a second).

Compare those results using timeit to the following direct execution of the same for-loop:

Evaluate a string to a formula in Google Sheets

Asked 2021-Jun-12 at 17:58

I am writing a math paper where i would like to display my calculations (formulas) separately from the solution.

I am currently working in Google Sheets.

The end goal would be to have one column with formulas and one column with answers.

I tried to work with GS to write a function that would take the string value from A1 and evaluate it in the B1 column.

I used this simple script that i found on: https://support.google.com/docs/thread/13826624/evaluate-string-as-formula?hl=en

ANSWER

Answered 2021-Jun-12 at 17:58

The easiest solution would probably be to work the other way around: write your formulas normally, and use the formulatext() spreadsheet function to display the formula in an adjacent cell.

ANSWER

Answered 2021-Jun-11 at 19:01

You can take advantage of the fact that if A is a matrix of shape (M, N), and b is a vector of shape (N, 1), then A.b equals a vector c of shape (M, 1).

A row x_c in c = sum((x_A, a row in A) * b).
