Number

Overview

A Number represents any 63-bit floating-point number. Internally, all values are encoded as tagged pointers where pointers with an initial bit of zero denote a floating-point value. As such, it should be noted there will be a minor loss of precision, approximately 15 decimal digits instead of ~15.95 for a full 64-bit double, with a mantissa of 51-bits.

Fields

`.sign`

fn -> Number

Gets the signum of a Number.

`.abs`

fn -> Number

Gets the absolute value of a Number.

`.ceil`

fn -> Number

Rounds a Number up to its nearest integer value.

`.floor`

fn -> Number

Rounds a Number down to its nearest integer value.

`.round`

fn -> Number

Rounds a Number to its nearest integer value.

`.trunc`

fn -> Number

Returns the integer part of a Number by removing any fractional digits.

`.clamp`

fn (minimum?: Number, maximum?: Number) -> Number

Ensures a Number is between two values, otherwise it returns the nearest boundary.

`.is_nan`

fn -> Boolean

Determines if a Number is represented by a NaN value.

`.is_fin`

fn -> Boolean

Determines if a Number is represented by a finite value.

`.is_inf`

fn -> Boolean

Determines if a Number is represented by an infinite value.

`.to_precision`

fn (digits?: Number) -> String

Converts a Number to a String with an optional number of significant digits.

`.to_scientific`

fn (digits?: Number) -> String

Converts a Number to a scientific String representation with an optional number of significant digits.

Statics

`.parse`

fn (input: String, radix?: Number) -> Number

Parses an input String, as a possible Number value. A radix value can be given to ensure parsing integer only values.
