Thanks guys for posting.
That helped me understand the lookup table.
Would it be faster and take up less code if I placed the table inside of an eeprom. Also to get the resolution I want over the temp. range I want, I think I am going to switch to a mcp 3202 12bit ad chip.

Another question for ya all. If I am reading a temp of 70.8 is it possible to store that in a 1 byte memory location. How I handle this now is to put the 70 in the high byte of a word variable and I put the .8 in the low byte.This works very well but doubles the memory requirments.

Thanks to You all
