Number

A Number object represents any numerical value, whether it is an integer or floating-point number. Generally, you do not need to worry about a Number object because a numerical value automatically becomes a Number object instance when you use a numerical value or assign it to a variable.

MAX_VALUE : Number

The largest representable Number.

MIN_VALUE : Number

The smallest representable Number.

NaN : Number

Not a Number.

NEGATIVE_INFINITY : Number

Negative infinite value; returned on overflow;

POSITIVE_INFINITY : Number

Negative infinite value; returned on overflow;

Number()

Constructs a Number.

Number(num : Number)

Constructs a new Number using the specified Number.

Number(value : String)

Constructs a Number using the specified value.

toExponential() : String

Converts this Number to a String using exponential notation.

toExponential(digits : Number) : String

Converts this Number to a String using exponential notation with the specified number of digits after the decimal place.

toFixed() : String

Converts a Number to a String that contains a no fractional part.

toFixed(digits : Number) : String

Converts a Number to a String that contains a specified number of digits after the decimal place.

toLocaleString() : String

Converts this Number to a String using local number formatting conventions.

toPrecision(precision : Number) : String

Converts a Number to a String using the specified number of signigicant digits.

toString() : String

A String representation of this Number.

toString(radix : Number) : String

Converts the number into a string using the specified radix (base).
