Sounds like basic fortran to me: http://www.cs.mtu.edu/~shene/COURSES...S/fortran.html

the returned error would be good to have.
Range for "a" and the formula "a"'s result is used in.

also remember that numbers without decimals will be treated like in INTEGER and truncated.
I do not remember that if the exponent is REAL then does the result calculate as REAL? Been forever since I used fortran.
