double sinh ( Integer num );
std::sinh for all cv-unqualified floating-point types as the type of the parameter.(since C++23)std::sinh on v_num.- (See math-floating-point and deduced-simd-t for their definitions.)
[edit] Parameters
[edit] Return value
If no errors occur, the hyperbolic sine of num (sinh(num), or-e-num
If a range error due to overflow occurs, ±HUGE_VAL , ±HUGE_VALF, or ±HUGE_VALL is returned.
If a range error occurs due to underflow, the correct result (after rounding) is returned.
[edit] Error handling
Errors are reported as specified in math_errhandling .
If the implementation supports IEEE floating-point arithmetic (IEC 60559),
- if the argument is ±0 or ±∞, it is returned unmodified.
- if the argument is NaN, NaN is returned.
[edit] 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<double>(num)).
[edit] Example
#include <cerrno> #include <cfenv> #include <cmath> #include <cstring> #include <iostream> // #pragma STDC FENV_ACCESS ON int main() { const double x = 42; std::cout << "sinh(1) = " << std::sinh(1) << '\n' << "sinh(-1) = " << std::sinh(-1) << '\n' << "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"; }
Output:
sinh(1) = 1.1752 sinh(-1) = -1.1752 log(sinh(42)+cosh(42)) = 42 sinh(+0) = 0 sinh(-0) = -0 sinh(710.5) = inf errno == ERANGE: Numerical result out of range FE_OVERFLOW raised
