Ever had this problem?
>> 0.1 + 0.2 0.30000000000000004
This solves that problem.
>> fixAfloat(0.1 + 0.2) 0.3
npm install fix-a-float
var fixAfloat = require('fix-a-float'); console.log(fixAfloat(0.1+0.2));
How does it do it?
It converts the number to a string, looks for a long run of zeros or nines at the end, removes them, and coverts back to a float.
Should I use this all the time, everywhere?
Absolutely not. Only use it in places where you need human readable numbers but don't know the precision you need. It doesn't actually solve any of the larger issues with floats.
