std::numeric_limits::radix(3) C++ Standard Libary std::numeric_limits::radix(3) NAME std::numeric_limits::radix - std::numeric_limits::radix Synopsis static const int radix; (until C++11) static constexpr int radix; (since C++11) The value of std::numeric_limits<T>::radix is the base of the number system used in the representation of the type. It is 2 for all binary numeric types, but it may be, for example, 10 for IEEE 754 decimal floating-point types or for third- party binary-coded decimal integers. This constant is meaningful for all spe- cializations. Standard specializations T value of std::numeric_limits<T>::radix /* non-specialized */ 0 bool 2 char 2 signed char 2 unsigned char 2 wchar_t 2 char8_t (since C++20) 2 char16_t (since C++11) 2 char32_t (since C++11) 2 short 2 unsigned short 2 int 2 unsigned int 2 long 2 unsigned long 2 long long (since C++11) 2 unsigned long long (since C++11) 2 float FLT_RADIX double FLT_RADIX long double FLT_RADIX See also digits number of radix digits that can be represented without change [static] (public static member constant) min_exponent one more than the smallest negative power of the radix that is a valid [static] normalized floating-point value (public static member constant) max_exponent one more than the largest integer power of the radix that is a valid [static] finite floating-point value (public static member constant) http://cppreference.com 2024.06.10 std::numeric_limits::radix(3)
