Calculates sines and hyperbolic sines.
double sin( double x ); float sin( float x ); // C++ only long double sin( long double x ); // C++ only float sinf( float x ); long double sinl( long double x ); double sinh( double x ); float sinh( float x ); // C++ only long double sinh( long double x ); // C++ only float sinhf( float x ); long double sinhl( long double x );
Parameters
x
Angle in radians.
The sin functions return the sine of x. If x is greater than or equal to 263, or less than or equal to –263, a loss of significance in the result occurs.
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 |
| ± ∞ (sin, sinf, sinl) | INVALID | _DOMAIN |
| |x| ≥ 7.104760e+002 (sinh, sinhf, sinhl) | OVERFLOW+INEXACT | OVERFLOW |
For more information about return codes, see errno, _doserrno, _sys_errlist, and _sys_nerr.
Because C++ allows overloading, you can call overloads of sin and sinh that take and return float or long double values. In a C program, sin and sinh always take and return double.
