Hyperbolic Functions
Many routines in the Intel® C++ Compiler Classic Math Library are more optimized for Intel® microprocessors than for non-Intel microprocessors.
The mathimf.h header file includes prototypes for Intel® C++ Compiler Classic Math Library functions.
The math library supports the following hyperbolic functions:
acosh
Description: The acosh function returns the inverse hyperbolic cosine of x.
errno: EDOM, for x < 1
Calling interface:
double acosh(double x);
long double acoshl(long double x);
float acoshf(float x);
asinh
Description: The asinh function returns the inverse hyperbolic sine of x.
Calling interface:
double asinh(double x);
long double asinhl(long double x);
float asinhf(float x);
atanh
Description: The atanh function returns the inverse hyperbolic tangent of x.
errno:
EDOM, for |x| > 1
ERANGE, for x = 1
Calling interface:
double atanh(double x);
long double atanhl(long double x);
float atanhf(float x);
cosh
Description: The cosh function returns the hyperbolic cosine of x, (ex + e-x)/2.
errno: ERANGE, for overflow conditions
Calling interface:
double cosh(double x);
long double coshl(long double x);
float coshf(float x);
sinh
Description: The sinh function returns the hyperbolic sine of x, (ex - e-x)/2.
errno: ERANGE, for overflow conditions
Calling interface:
double sinh(double x);
long double sinhl(long double x);
float sinhf(float x);
sinhcosh
Description: The sinhcosh function returns both the hyperbolic sine and hyperbolic cosine of x.
errno: ERANGE, for overflow conditions
Calling interface:
void sinhcosh(double x, double *sinval, double *cosval);
void sinhcoshl(long double x, long double *sinval, long double *cosval);
void sinhcoshf(float x, float *sinval, float *cosval);
tanh
Description: The tanh function returns the hyperbolic tangent of x, (ex - e-x) / (ex + e-x).
Calling interface:
double tanh(double x);
long double tanhl(long double x);
float tanhf(float x);
