std::numeric_limits<T>::has_infinity: std::numeric_limits<T>::has_infinity

NAME

std::numeric_limits<T>::has_infinity - std::numeric_limits<T>::has_infinity

Synopsis

static const bool has_infinity; (until C++11)
static constexpr bool has_infinity; (since C++11)

The value of std::numeric_limits<T>::has_infinity is true for all types T capable of representing the positive infinity as a distinct special value. This constant is meaningful for all floating-point types and is guaranteed to be true if std::numeric_limits<T>::is_iec559 == true.
