Defined in header
template<classInteger>doublesinh(Integernum); (A)(constexpr since C++26)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)
A) Additional overloads are provided for all integer types, which are treated as double.
(since C++11)Parameters
num - floating-point or integer value Return value
If no errors occur, the hyperbolic sine of num (sinh(num), or
enum
-e-num
2
) is returned.
If a range error due to overflow occurs,
, ±HUGE_VALF, or ±HUGE_VALL is returned.
If a range error occurs due to underflow, the correct result (after rounding) is returned.
Error handling
Errors are reported as specified in
.
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.
Notes
that in case of underflow, num is returned unmodified, and if that is not supported, and implementation-defined value no greater than
,
, and
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)).
