std::isgreaterequal(3) C++ Standard Libary std::isgreaterequal(3) NAME std::isgreaterequal - std::isgreaterequal Synopsis Defined in header <cmath> bool isgreaterequal( float x, float y ); (since C++11) bool isgreaterequal( double x, double y ); (until C++23) bool isgreaterequal( long double x, long double y ); constexpr bool isgreaterequal( /* floating-point-type */ x, (1) (since C++23) /* floating-point-type */ y ); Additional overloads Defined in header <cmath> template< class Arithmetic1, class Arithmetic2 > (A) (since C++11) bool isgreaterequal( Arithmetic1 x, Arithmetic2 y ); (constexpr since C++23) 1) Determines if the floating point number x is greater than or equal to the floating-point number y, without setting floating-point exceptions. The library provides overloads for all cv-unqualified floating-point types as the type of the parameters x and y. (since C++23) A) Additional overloads are provided for all other combinations of arithmetic types. Parameters x, y - floating-point or integer values Return value true if x >= y, false otherwise. Notes The built-in operator>= for floating-point numbers may raise FE_INVALID if one or both of the arguments is NaN. This function is a "quiet" version of op- erator>=. The additional overloads are not required to be provided exactly as (A). They only need to be sufficient to ensure that for their first argument num1 and second argument num2: * If num1 or num2 has type long double, then std::isgreaterequal(num1, num2) has the same effect as std::isgreaterequal(static_cast<long double>(num1), static_cast<long double>(num2)). * Otherwise, if num1 and/or num2 has type double or an integer type, then std::isgreaterequal(num1, num2) has the same effect as (until std::isgreaterequal(static_cast<double>(num1), C++23) static_cast<double>(num2)). * Otherwise, if num1 or num2 has type float, then std::is- greaterequal(num1, num2) has the same effect as std::isgreaterequal(static_cast<float>(num1), static_cast<float>(num2)). If num1 and num2 have arithmetic types, then std::isgreaterequal(num1, num2) has the same effect as std::isgreaterequal(static_cast</* common-floating-point-type */>(num1), static_cast</* common-floating-point-type */>(num2)), where /* common-floating-point-type */ is the floating-point type with the greatest floating-point conversion rank and greatest floating-point (since conversion subrank between the types of num1 and num2, arguments of in- teger C++23) type are considered to have the same floating-point conversion rank as double. If no such floating-point type with the greatest rank and subrank ex- ists, then overload resolution does not result in a usable candidate from the overloads provided.
