Sqrt, float, nan issue

[valkan]

Hi,
What should I do to avoid nan result of calculation?

Here is what I am doing:
Serial.print (sqrt((0-110)*(0-110)+(0-110)*(0-110)+(0-110)*(0-110)));
This is printing nan.

Same thing in Eclipse return actual number: 190.526

Thanks.

Well, both the intermediate products and the final sum before taking the root are values that won't fit in a 16 bit int.
Try declaring them as floats, or giving them all ".0", and see what that does for you.

This is printing nan.

Lose the "sqrt()" in your print, and all will be revealed

one float saves the day...

Serial.println (sqrt((0 - 110.0) * (0 - 110) + (0 - 110) * (0 - 110) + (0 - 110) * (0 - 110)));

Hi, you are correct, I was out of range.
Thank you.
