Try A*100/B - will have the same end effect to getting a percent - of =
course no decimal places.

I'm using Bytecraft's compiler for MPLAB.  it does basic math, but the
results I'm getting indicate that it is droping anything after the integer
on my calculations.  I'm trying to calculate a percentage:

Percent =3D A/B * 100;  something like that.  I have been getting a zero =
for
percent everytime.

What are you trying to do?  Float <--> integer conversion is just a matter
of casting, and I haven't seen a C compiler recently that didn't support
basic operations (+,-,/,*).  Standard C math functions will do a lot...
are you using a compiler without floating point support?
