 ACos = val " ACOS():128"

Required Arguments:

Name: Arg1

Type: vDouble

An argument that specifies the operand of the calculation.

Return Value:

Type: PtgAngDft, PtgErr

This function returns a PtgAngDft containing the arccosine of the value of Arg1. If Arg1 is less than ­1 or greater than 1, the function returns a PtgErr with an error code of #VALUE!.
