Interesting. I didn't know that.
Hisoft Basic compiled code either uses the ROM or something identical to calculate the circles then. Huh.
I just found <!-- m --><a class="postlink" href="http://www.andreadrian.de/oldcpu/Z80_number_cruncher.html">http://www.andreadrian.de/oldcpu/Z80_nu ... ncher.html</a><!-- m -->, and then noticed you've borrowed code from that. I'm looking at the 16.16 routines with interest. Might be able to work those up as functions for a library, on the assumption that users looking for speed will be willing to sacrifice accuracy, and use FIXED type numbers.
