Math.abs

static function Math.abs(number : Number) : Number

Arguments

number
The number for which to return the absolute value.

Returns

Returns the absolute value of a number.

Description

Returns the absolute value of a number.

Math.acos

static function Math.acos(number : Number) : Number

Returns

Returns the arc cosine of a number.

Description

Returns the arc cosine of a number, where number must be between -1 and 1. If number is not between -1 and 1, the function returns NaN. Param: The number for which to return the arc cosine.

Math.asin

static function Math.asin(number : Number) : Number

Arguments

number
The number for which to return the arc sine.

Returns
