    Code:
    ADCIN 4, volt                  ' Read AN4 into temp variable
volt = volt * 2
Vin = (5*volt/1023)
Vind = (volt // 1000) / 10 'millivolts?

lcdout $FE, $C0+8, dec Vin,".",dec2 Vind,"V"
    Time to pack it in for the night, work tomorrow, fairly good progress, just the decimal points to figure out.

    Kind Regards

    Ok Rob,

    What about :

    Code:
    ADCIN 4, volt                  ' Read AN4 into temp variable

volt = volt * 2 * 5

Volt = 100*volt               ' See manual for DIV32 !!!
Vind = DIV32 1024           ' Here we have result in 1/100 Volts ...

Vin = Vind/100                  ' Here we get the integer part ...
Vind = Vind // 100             ' Here we get the decimal part ...

lcdout $FE, $C0+8, dec Vin,".",dec2 Vind,"V"
    that's all !

    Why insist on using 32 Bits when you're not even able to deal with the first 8 ones ??? ehhhhhh ...

    IF there is the word "Problem" in your question ...
    certainly the answer is " RTFM " or " RTFDataSheet " !!!
