Detailed Description

template<typename Scalar>
class OpenMesh::Utils::NumLimitsT< Scalar >

This class provides the maximum and minimum values a certain scalar type (int, float, or double) can store. You can use it like this:

    #include <OpenMesh/Utils/NumLimitsT.hh>

    int   float_min   = OpenMesh::NumLimitsT<float>::min();
    float double_max  = OpenMesh::NumLimitsT<double>::max();

Note:

This functionality should be provided by std::numeric_limits. This template does not exist on gcc <= 2.95.3. The class template NumLimitsT is just a workaround.
