Hi,

I'm trying to create a digital thermometer which shows the current =
temperature on a LCD. I was thinking of using the LM335 as the =
temperature probe, as it is a linear temperate/voltage relationship. I =
was planning on using  the PIC16F877 because of the 10 Bit ADC and the =
vast number of IO pins.

My problem is, I have only used basic Asm before, and finding how to do =
this in any other language is also difficult, as I must somehow do:

ADC Ouput (10bit)/ Vref (10bit)=3D A number here. Divide by Vref to get =
an accurate temperature even if the voltage isn't as constant as one =
would like.
Then substitute it into a formula like:

0.15 + (3 * output above) to find the temperature.

Does anyone know how to do this, or an easier way of doing this. I've =
been looking around and i can't find how PIC's would represent =
fractions, and how to substitute into formulas like the above.=20

Thanks,
-Peter
