std::numeric_limits::infinity - cppreference.com (original) (raw)

| static T infinity() throw(); | | (until C++11) | | --------------------------------------- | | ------------- | | static constexpr T infinity() noexcept; | | (since C++11) |

Returns the special value "positive infinity", as represented by the floating-point type T. Only meaningful if std::numeric_limits<T>::has_infinity == true. In IEEE 754, the most common binary representation of floating-point numbers, the positive infinity is the value with all bits of the exponent set and all bits of the fraction cleared.
