Standard C++ Library Class Reference

static const bool

traps ;

This field is true if trapping is implemented for this type. The traps field is meaningful for

all specializations.

Example

// limits.cpp

#include <limits>

int main()

{

numeric_limits<float> float_info;

if (float_info.is_specialized && float_info.has_infinity)

{

// get value of infinity

float finfinity=float_info.infinity();

}

return 0;

}

Warning

The specializations for wide chars and bool will only be available if your compiler has

implemented them as real types and not simulated them with typedefs.
