How to get a fraction from a float number?

Question

I have a floating point number:

var f = 0.1457; 

Or:

var f = 4.7005 

How do I get just the fraction remainder as integer?

I.e. in the first example I want to get:

var remainder = 1457; 

In the second example:

var remainder = 7005; 

Answer 1

function frac(f) {     return f % 1; } 

hope that helps ;-)

Answer 2

While this is not what most people will want, but TS asked for fract as integer, here it is:

function fract(n){ return Number(String(n).split('.')[1] || 0); } fract(1.23) // = 23 fract(123) // = 0 fract(0.0008) // = 8
