Hi netters!

I a recent article on coprocessors for 80x86 systems I posted to 
comp.sys.ibm.pc.hardware I claimed that installing a math coprocessor
does not speed up GUIs (MS-Windows, OS/2 Presentation Mgr, X-Windows),
since these use only integer math internally. However, people have
told me that some GUIs indeed use fp math for stuff like arc drawing
and similar operations. Does anyone know for sure whether OS/2's GUI
benefits by installing a coprocessor. Please send email, as I do not
usually read this group. I'll post a summary of responses I get, if I
get any. Thanx in advance!

Norbert
