sinh, sinhf, sinhl

Defined in header <math.h>
float       sinhf( float arg );
+
(1) (since C99)
double      sinh( double arg );
+
(2)
long double sinhl( long double arg );
+
(3) (since C99)
Defined in header <tgmath.h>
#define sinh( arg )
+
(4) (since C99)
+1-3) Computes hyperbolic sine of arg.
+4) Type-generic macro: If the argument has type long double, sinhl is called. Otherwise, if the argument has integer type or the type double, sinh is called. Otherwise, sinhf is called. If the argument is complex, then the macro invokes the corresponding complex function (csinhf, csinh, csinhl).

Parameters

+ +
arg - floating point value representing a hyperbolic angle

Return value

If no errors occur, the hyperbolic sine of arg (sinh(arg), or earg-e-arg/2) is returned.

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.

+

Error handling

Errors are reported as specified in math_errhandling.

+

If the implementation supports IEEE floating-point arithmetic (IEC 60559),

+

Notes

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

+

Example

#include <stdio.h>
+#include <math.h>
+#include <errno.h>
+#include <fenv.h>
+ 
+// #pragma STDC FENV_ACCESS ON
+int main(void)
+{
+    printf("sinh(1) = %f\nsinh(-1)=%f\n", sinh(1), sinh(-1));
+    printf("log(sinh(1) + cosh(1))=%f\n", log(sinh(1)+cosh(1)));
+    // special values
+    printf("sinh(+0) = %f\nsinh(-0)=%f\n", sinh(0.0), sinh(-0.0));
+    // error handling 
+    errno=0; feclearexcept(FE_ALL_EXCEPT);
+    printf("sinh(710.5) = %f\n", sinh(710.5));
+    if(errno == ERANGE) perror("    errno == ERANGE");
+    if(fetestexcept(FE_OVERFLOW)) puts("    FE_OVERFLOW raised");
+}

Possible output:

+
sinh(1) = 1.175201
+sinh(-1)=-1.175201
+log(sinh(1) + cosh(1))=1.000000
+sinh(+0) = 0.000000
+sinh(-0)=-0.000000
+sinh(710.5) = inf
+    errno == ERANGE: Numerical result out of range
+    FE_OVERFLOW raised
