Does your method have some kind of cumulative error? I fixed the invalid xhtml bug, thanks for the info.
There's no place like ::1

Yes, but with 64-bit floating point it's not too large. The multiply-adds should also help a bit (just 10 FP instructions on PPC, not 14, BTW). Here's what a 1000000-gon looks like at the point of the largest error (Z):
Code: Select all
M 373.205081 300.000000
L 373.204767 300.000544
L 373.204138 300.001632
...
L 373.205709 299.998912
L 373.205395 299.999456
Z
Close enough?

I guess… It's all going to be converted to 32-bit floats in arma, anyways.
