Hi All Does anybody know of good and easy to using floating point routines for the PIC16C series ?. The Microchip app notes are good, but I need help with the conversion of real time variables (not constants) in my code to the floating format and back again. For example I will have a binary value from and A/D converter and I know where the exponent is. This must now be converted to floating point. Now I will do some mathematical manipulation with a few constants and the answer must now be converted back to either a binary of BCD format for a LCD display. I then read the exponent of the result and add the decimal position to the display. Any help or where to find these routines will be appreciated Many thanks Mike
