Trying to use exp but getting error

I have a calculation with exp. I am trying to run on the Nano but I am getting an error of 'EXP' was not declared in this scope. I tried to do a search but didn't find anything.

This is the calculation
Pw = (RH/100)EXP(17.863-9621/(T+460))
W= 7000
0.62198/(29.92/Pw-1)

Thanks,
Kevin

I added #include "math.h" but still getting the same error EXP' was not declared in this scope.

Gander at the title of the first hint. What is different from your version?

Not sure I follow, unless I need to declare exp as int, float etc. Never worked with this before.

Thanks,
