Number Formatting in JavaScript

Syntax:

Rounding floating-point numbers

15.345.toFixed(2); // returns "15.35" (rounding!)

15.3.toFixed(2); // returns "15.30" (zero padding)

Exponential form

The equivalent of sprintf("%.2e", num) is num.toExponential(2).

33333 .toExponential(2); // "3.33e+4"

// ^ Note the space, which keeps the . from being a decimal point.

// Leaving out the space is a syntax error :-(
