Error: identifier "MAXFLOAT" is undefined

Question

I am trying to convert a Xcode project (link) to a VS2008 solution.

In a cuda filetype .cu, the term MAXFLOAT is used. I am adding the following headers but the error is not resolved.

#include <stdio.h>
#include <math.h>

In the Xcode project, I tried to locate the definition but there is none. Also this term is only used in this file. Is this something specific to Xcode?

Answer 1

MAXFLOAT is a non-standard parameter. Use one of the following, portable alternatives:

• In C: use the standard library FLT_MAX (defined in <float.h>).

• In C++: use std::numeric_limits<float>::max (defined in <limits>). You may still use C's FLT_MAX, but include <cfloat> instead.
