sinh, sinhf, sinhl

Calculates the hyperbolic sine.

Syntax

double sinh(double x);
float sinhf(float x);
long double sinhl(long double x);
float sinh(float x);  // C++ only
long double sinh(long double x);  // C++ only

Parameters

x
Angle in radians.

Return Value

The sinh functions return the hyperbolic sine of x. By default, if the result is too large, sinh sets errno to ERANGE and returns ±HUGE_VAL.

Input SEH Exception Matherr Exception
± QNAN,IND None _DOMAIN
|x| ≥ 7.104760e+002 OVERFLOW+INEXACT OVERFLOW

For more information about return codes, see errno, _doserrno, _sys_errlist, and _sys_nerr.

Remarks

Because C++ allows overloading, you can call overloads of sinh that take and return float or long double values. In a C program, sinh always takes and returns double.

Requirements

Example

// crt_sinhcosh.c
// This program displays the hyperbolic
// sine and hyperbolic cosine of pi / 2.
// Compile by using: cl /W4 crt_sinhcosh.c

#include <math.h>
#include <stdio.h>

int main( void)
{
   double pi = 3.1415926535;
   double x, y;

   x = pi / 2;
   y = sinh( x );
   printf( "sinh( %f ) = %f\n",x, y );
   y = cosh( x );
   printf( "cosh( %f ) = %f\n",x, y );
}
sinh( 1.570796 ) = 2.301299
cosh( 1.570796 ) = 2.509178
