ACOS()

The ACOS() function returns the arc-cosine (inverse cosine) of a value.

Format

ACOS(expr)

where

The ACOS() function returns the arc-cosine of expr. Angles are measured in degrees.

If expr is a numeric array (a dynamic array where all elements are numeric), the ACOS() function operates on each element in turn and returns a numeric array with the same structure as expr.

Examples

ANGLE = ACOS(ADJ / HYP)

This statement finds the angle with cosine equal to the value of ADJ / HYP and assigns this to variable ANGLE.
