Distinguishing integer from floating point types in a template

Question

I\'d like to perform similar, but not identical computations for several integer types (16, 32, 64 bits) and floating point types (float, double, long double). Most of the code

Answer 1

Yes, you can use SFINAE in combination with the metafunctions from

#include

template
typename std::enable_if<
    std::is_integral::value,
    bool>::type

isEqual(IntegralType a,IntegralType b)
{
    return a == b;
}

template
typename std::enable_if<
    std::is_floating_point::value,
    bool>::type

isEqual(FloatingType a,FloatingType b)
{
    return fabs(a-b) <  std::numeric_limits::epsilon();
}
