Question

I’m facing a problem to get the digit of a number after decimal point. I need the digit to do if else statement.

Here is an example:

31.30 = 31.30
31.31 = 31.30
31.32 = 31.30
31.33 = 31.35
31.34 = 31.35
31.35 = 31.35
31.36 = 31.35
31.37 = 31.35
31.38 = 31.40
31.39 = 31.30   

So, I need to get the second digit after decimal point. Then, i can use the digit to do if else statement. This rounding issue is happening in Malaysia.

Answer 1

Something like this might work for doing the rounding to the nearest 5 cents, although then you may need to format the output to have the proper number of digits past the decimal point:

var origVal = 31.34;
var roundedVal = Math.round(origVal*20)/20;

Which would give you 31.35, i.e., rounded to the nearest nickel.

This seems a little more direct than getting the digit and doing an if/else.
