[comp.lang.pascal] Built in graphics routines in TP

F0O@psuvm.psu.edu (02/20/91)

     I was wondering if anyone knows if the built in BGI routines will
use a numeric co-processor if it is installed, or is it all done in
software?

Since most graphics primitives (draw line, draw ellipse, etc.) can be 
performed with integer arithmetic (which is much faster than floating
point even with a coprocessor) I expect that the BGI routines don't use
a coproc and don't need one.
