xcall FP_ARCCOS(result, operand)

Arguments

result

Returned with the arc cosine of operand. (a8)

operand

The radian value whose arc cosine will be returned. (a8)

Discussion

The FP_ARCCOS subroutine returns the arc cosine of a floating‑point number.

The following operation is performed:

result = arccos(operand)

Result and operand are native floating‑point numbers represented as a8 variables.
