Number.prototype.toFixed()

The toFixed() method of Number values returns a string representing this number using fixed-point notation with the specified number of decimal places.

The toFixed() method returns a string representation of a number without using exponential notation and with exactly digits digits after the decimal point. The number is rounded if necessary, and the fractional part is padded with zeros if necessary so that it has the specified length.

If the absolute value of the number is greater or equal to 1021, this method uses the same algorithm as Number.prototype.toString() and returns a string in exponential notation. toFixed() returns “Infinity”, “NaN”, or “-Infinity” if the value of the number is non-finite.
