DXL has sin, cos and tan functions, but does anyone know how I can get the arc tan (i.e tan-1) of a value, Have tried atan, aTan, arcTan, invTan all to no avail, Any ideas?
I'm trying to calculate an angle given the x and y co-ordinates.

Thanks Ron, I'll give that a go.
Can't believe that DXL has built in functions for sin, cos & tan, but not the corresponding arc functions!
