> How about just using a look up table?

This might be a stupid question, but what exactly is a lookup table. Recently,
I have been reading a lot of posts dealing with lookup tables. Is it just a
table basically stored in RAM/EEPROM that can be used to obtain a value from a
calculation instead of coding math routines? At the expense of code space of
course...

Correct me if I'm wrong please.
