[Insight-users] data type limits

[Dan Mueller]

Hi Darren,

If I understand your question correctly, I believe you may be looking
for itk::NumericTraits.

You can use as follows:

#include "itkNumericTraits.h"

typedef unsigned char PixelType;

std::cout << "max=" << itk::NumericTraits<PixelType>::max() << std::endl;
std::cout << "min=" << itk::NumericTraits<PixelType>::min() << std::endl;
std::cout << "zero=" << itk::NumericTraits<PixelType>::Zero << std::endl;
std::cout << "one=" << itk::NumericTraits<PixelType>::One << std::endl;
std::cout << "one=" << itk::NumericTraits<PixelType>::IsPositive( 42 )
<< std::endl;
etc...

Hope this helps.

Cheers, Dan
