I converted the 32-bit version to PIC18. I don't think I used all of the
functions, but the ones I used worked well.
In the file are also my INTEGER->BCD conversion functions.
Int24_Flo32 - 24 bit integer to 32 bit floating point conversion
Flo32_Int24 - 32 bit floating point to 24 bit integer conversion
Int32_Flo32 - 32 bit integer to 32 bit floating point conversion
Flo32_Int32 - 32 bit floating point to 32 bit integer conversion
Flo32_Add - 32 bit floating point add
Flo32_Sub - 32 bit floating point subtract
Flo32_Mul - 32 bit floating point multiply
Flo32_Div - 32 bit floating point divide
Bin24_BCD - 24-BIT BINARY TO EIGHT BCD DIGITS (230 cycles)
WordBCD - 16-BIT BINARY TO FIVE BCD DIGITS (65 cycles)
Hope this helps,
