Converting number into string in JavaScripts without trailing zeros from number

Question

I tried to convert number to string in JavaScripts using toString() but it truncates insignificant zeros from numbers. For examples;

var n1 = 250.00 
var n2 = 59         


        

Answer 1

The number doesn't know how many trailing 0 there are because they are not stored. In math, 250, 250.00 or 250.0000000000000 are all the same number and are all represented the same way in memory.

So in short, there is no way to do what you want. What you can do is format all numbers in a specific way. See Formatting a number with exactly two decimals in JavaScript.
