Returns the arccosine of a numeric expression.

Syntax
Acos(number)

Parameters

number

Specify the cosine of the angle as a real number value.

Return Values
Real value, in radians, representing the arccosine of the parameter number.

Description
Acos returns the arccosine of the numeric expression. Values range is from -1 to -1. The value returned by Acos will range from 0 to PI radians. If number is -1 or 1, an error occurs.

To convert from radians to degrees, use the RadToDeg function.
