How do I find the max double on my FC4?
Thanks,
Mike.
Mia culpa. I see that I did not clearly state my question.
What include file and macro should I use to get the max
double in a c++ program?
Thanks again,
Mike.
#include <math.h>
Don't need that one.
#include <float.h>
Do need that one, though #include <cfloat> is preferred for C++.
Also need <cstdio> or <stdio.h> for C-style i/o or <iostream> for C++
stream i/o.
then reference "LDBL_MAX"
DBL_MAX for doubles, LDBL_MAX for long doubles.
If you use C-style i/o, be careful about format specifiers for printf()
when printing long doubles (or long anything).
