I had good results using Microchips fixed point AN617, and floating
point AN575 math libraries. You may also be interested in the floating
point to ascii conversion AN670. I used portions of all three for a lcd
frequency meter display and was very impressed with the results. I'm not
familiar with the PIC16F630, but the math routines used about 1k of
program memory.
