How do I replace NaN with 0 when doing division in javascript?

Hope that helps I am trying to do simple division using .map() on an array of objects. However when zero divided by zero returns NaN. How to I check for this calculation and return the number 0 instead of NaN? , You don't need to explicitly check. This should be your line 10:
code :
interactiveLeadConversations: (((data.sent / data.interactive) || 0) * 100).toFixed(0)
(data.sent / data.interactive)
( (data.sent / data.interactive) || 0 )

it fixes the issue This is probably the fastest solution, but the where function does trigger the error as it precalculates the solutions:
code :
import numpy as np

n = 4

xy = np.random.randint(4, size=(n,n)).astype(float)
x_norm = np.random.randint(4, size=(n,n)).astype(float)
y_norm = np.random.randint(4, size=(n,n)).astype(float)

xy_norm = x_norm*y_norm

edge_map = np.where(xy_norm == 0, xy_norm, xy/xy_norm)

print(xy)
print(xy_norm)
print(edge_map)

fixed the issue. Will look into that further , Include jQuery in your page and use the following code block
code :
$(document).ready(function() {
     $('button').on('click', function() {
         alert($(this).closest('div').find('h3').text());
     });
 });

I wish this helpful for you I have a data.frame that looks like:
code :
library(data.table)
data<-fread("a   b  c   d
1   2  NA  1
            NA  2  2   1 
            3   2  NA  1
            NA  NA 20  2")
names_to_loop<-names(data)
names_to_loop<-names_to_loop[names_to_loop!="c"&names_to_loop!="d"]
for (ntl in names_to_loop){
  set(data,j=ntl,value=ifelse(is.na(data[[ntl]]),data[["c"]]/data[["d"]],data[[ntl]]))
}
data[,c:=NULL]
data[,d:=NULL]
> data
    a  b
1:  1  2
2:  2  2
3:  3  2
4: 10 10

Javascript division error using division operator

I hope this helps . Floating point arithmetic in Javascript is broken and in general as well.
It has nothing to do with division, it will return false if you don't do division since you are checking float value.
