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 operator>=.
   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::isgreaterequal(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 integer 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 exists,
   then overload resolution does not result in a usable candidate from the
   overloads provided.
