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;
function frac(f) {
return f % 1;
}
hope that helps ;-)
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
This will do it (up to the 4 digits that you want, change the multipler (10000) to larger or smaller if you want smaller or larger number):
Math.ceil(((f < 1.0) ? f : (f % Math.floor(f))) * 10000)
