xcall FP_ARCSIN(result, operand)

Arguments

result

Returned with the arc sine of operand. (a8)

operand

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

Discussion

The FP_ARCSIN subroutine returns the arc sine of a floating-point number.

The following operation is performed:

result = arcsin(operand)

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