cos, cosf, cosh, coshf
Visual Studio 2008
Calculate the cosine (cos or cosf) or hyperbolic cosine (cosh or coshf).
double cos( double x ); float cos( float x ); // C++ only long double cos( long double x ); // C++ only float cosf( float x ); double cosh( double x ); float cosh( float x ); // C++ only long double cosh( long double x ); // C++ only float coshf( float x );
The cosine or hyperbolic cosine 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 of a call to cos occurs.
If the result is too large in a cosh or coshf call, the function returns HUGE_VAL and sets errno to ERANGE, by default.
