std::sinh, std::sinhf, std::sinhl

Since C++26

Header: <cmath>

1-3) Computes the hyperbolic sine of num.The library provides overloads of std::sinh for all cv-unqualified floating-point types as the type of the parameter.(since C++23)

# Declarations

float sinh ( float num );
double sinh ( double num );
long double sinh ( long double num );

(until C++23)

/*floating-point-type*/
sinh ( /*floating-point-type*/ num );

(since C++23) (constexpr since C++26)

float sinhf( float num );

(since C++11) (constexpr since C++26)

long double sinhl( long double num );

(since C++11) (constexpr since C++26)

SIMD overload (since C++26)

template< /*math-floating-point*/ V >
constexpr /*deduced-simd-t*/<V>
sinh ( const V& v_num );

(since C++26)

Additional overloads (since C++11)

template< class Integer >
double sinh ( Integer num );

(constexpr since C++26)

# Parameters

# Return value

If a range error due to overflow occurs, ±HUGE_VAL, ±HUGE_VALF, or ±HUGE_VALL is returned.

# Notes

POSIX specifies that in case of underflow, num is returned unmodified, and if that is not supported, and implementation-defined value no greater than DBL_MIN, FLT_MIN, and LDBL_MIN is returned.

The additional overloads are not required to be provided exactly as (A). They only need to be sufficient to ensure that for their argument num of integer type, std::sinh(num) has the same effect as std::sinh(static_cast(num)).

# Example

#include <cerrno>
#include <cfenv>
#include <cmath>
#include <cstring>
#include <iostream>
// #pragma STDC FENV_ACCESS ON

              << "log(sinh(" << x << ")+cosh(" << x << ")) = "
              << std::log(std::sinh(x) + std::cosh(x)) << '\n';
 
    // special values
    std::cout << "sinh(+0) = " << std::sinh(0.0) << '\n'
              << "sinh(-0) = " << std::sinh(-0.0) << '\n';
 
    // error handling
    errno = 0;
    std::feclearexcept(FE_ALL_EXCEPT);
 
    std::cout << "sinh(710.5) = " << std::sinh(710.5) << '\n';
 
    if (errno == ERANGE)
        std::cout << "    errno == ERANGE: " << std::strerror(errno) << '\n';
    if (std::fetestexcept(FE_OVERFLOW))
        std::cout << "    FE_OVERFLOW raised\n";
