Synopsis. For each function with at least one parameter of type /* floating-point-type */, an overload for each cv-unqualified floating-point type is provided where all uses of /* floating-point-type */ in the function signature are replaced with that floating-point type.. For each function with at least one parameter of type /* floating-point-type */ other than std::abs, additional overloads ...

Beta4-9) Computes the nearest integer value to num (in integer format), rounding halfway cases away from zero, regardless of the current rounding mode. The library provides overloads of std::lround and std::llround for all cv-unqualified floating-point types as the type of the parameter num. (since C++23)

BetaNotes. A program that instantiates a primary template of a mathematical constant variable template is ill-formed. The standard library specializes mathematical constant variable templates for all floating-point types (i.e. float, double long double, and fixed width floating-point types (since C++23)). A program may partially or explicitly specialize a mathematical constant variable template ...
