HI all.

I'm experimenting with the HM55B Compass Module,
on the HM55ModDocs.pdf in the SX section it is indicated the possibility to obtain the real angle from North in Degree.
The suggested operation is:  [b]arctan(-y/x)[/b]
But there is no such command or operator in the SX/B.
I have done a search in the Forum but with no results.........
How can I obtain the arctan calculation with SX?

Anyone has a suggestion on how to accomplish this?

Thanks in Advance

Stefano

P.S. Excuse my fat ignorance about math's
