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

Returns the arc sine of a number.

Description

Returns the arc sine of a number, where number must be between -1 and 1. If number is not between -1 and 1, the function returns NaN.

Math.atan

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

Arguments

number
The number for which to return the arc tangent.

Returns

Returns the arc tangent of a number.

Description

Returns the arc tangent of a number.

Math.atan2

Description

Returns the arc tangent of y/x.

Math.ceil

static function Math.ceil(number : Number) : Integer

Arguments

number
The number for which to find the smallest integer greater than it.

Returns

Returns the smallest integer greater than the number.

Description

Returns the smallest integer greater than a number.

Math.cos

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

Arguments

number
The number for which to return the cosine.

Returns

Returns the cosine of a number.

Description

Returns the cosine of a number.

Math.exp

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

Arguments

number
The number to raise e to the power of.

Returns

Returns e to the power of a number.

Description
