- 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.
[edit] Parameters
| x, y | - | floating-point or integer values |
|---|
[edit] Return value
true if x >= y, false otherwise.
[edit] 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 std::isgreaterequal(static_cast<double>(num1), 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)). | (until C++23) |
|---|---|
| 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 conversion subrank between the types of num1 and num2, arguments of integer 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. | (since C++23) |
