Help with function

[Brian T. Schellenberger]

Aside from the fact, ast pointed out already, that strtod() is
returning a decimal rather than a double, abs() returns, and expects,
a decimal as well.  Use fabs().*

*Actually, abs() on many systems is "generic," but it isn't required to be.
strtod never is.
