A Double between 0 and pi that is the arccosine of d in radians
Returns the arccosine of d in radians
If d is out of range (less than -1 or greater than 1), Acos returns NaN .
This is a Shared member, so it can be used without creating any objects.
To convert from radians to degrees, multiply by 180/pi.
The Acos function did not exist in VB 6.
