parseFloat rounding

Use toFixed() to round num to 2 decimal digits using the traditional rounding method. It will round 4.050000000000001 to 4.05. num.toFixed(2); You might prefer using toPrecision(), which will strip any resulting trailing zeros. Example: 1.35+1.35+1.35 => 4.050000000000001 (1.35+1.35+1.35).toFixed(2) => 4.05 (1.35+1.35+1.35).toPrecision(3) => 4.05 // or… (1.35+1.35+1.35).toFixed(4) => 4.0500 (1.35+1.35+1.35).toPrecision(4) => 4.05 Reference: JavaScript Number Format … Read more
