Tests:

Native
var a = 0.1; var b = 0.2; ((a + b) * b).toString();
Native + toFixed
var a = 0.1; var b = 0.2; ((a + b) * b).toFixed(9);
Big.js
var a = new Big("0.1"); var b = new Big("0.2"); a.plus(b).mul(b).toString();
Fraction.js
var a = new Fraction("0.1"); var b = new Fraction("0.2"); a.add(b).mul(b).toString();
number-precision
var a = 0.1; var b = 0.2; NP.times(NP.plus(a, b), b).toString()
