  • 32 arithmetic

    Is there any code available for simple 32 bit arithmetic? +,-,* and / would do.
    I got 32bit binary numbers coming on the comms port and need to reformat them into the 16 bit variable sizes available.

    Thanks for your help

    If you need 16bit can you not do the maths on the first 2 bytes as a 16bit number then the same on the 2nd 2 - first 2 then make the highbyte / second 2 the low byte of the scaled 16bit answer

      Thanks for that. It's not very difficult to do it. I was just hoping someone came across that before and made some code library.
      I'm just lazy and don't want to repeat done stuff. 32 bit numbers is a pretty standard format after all.
      I'll just write up the functions I'll need.
