I'm developing a program that does a lot of floating point calculations.  Even
though I have a math chip (80387SX), I'd like to disable the math chip so I
can see what performance users lacking the math chip will experience.

I'm using BC++ 2.0, which I believe uses a math chip emulation library
built into Windows.  So can the user of the math chip by the library

-- let me try again --

So can one force the library to emulate a math chip in software even if
one is installed?  If so, how?  If I have to write a small program, that's
no problem...



ADV thanks ANCE,
