sinhl is called. Otherwise, if the argument has integer type or the typedouble,sinh is called. Otherwise,sinhf is called. If the argument is complex, then the macro invokes the corresponding complex function (csinhf,csinh,csinhl).Contents |

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.
Errors are reported as specified inmath_errhandling.
If the implementation supports IEEE floating-point arithmetic (IEC 60559),
POSIX specifies that in case of underflow,arg is returned unmodified, and if that is not supported, an implementation-defined value no greater thanDBL_MIN,FLT_MIN, andLDBL_MIN is returned.
