#96759 - calculating square roots Responding to: ???'s previous message |
This was discussed: http://www.8052.com/forum/read.phtml?id=82754 Or you can simply use a lookup table if you've got some code space. You only need to have a small range of input values as you have a fair idea of the expected voltages you expect to measure so your table can be quite compact - maybe smaller than the code needed to calculate the square root! You want sample code for this??? Errr, I think we'll leave that as an exercise for the person asking the question! |
