NAME

asinh — inverse hyperbolic sine function

SYNOPSIS

#include <math.h>

double
asinh(double x);

long double
asinhl(long double x);

float
asinhf(float x);

DESCRIPTION

The asinh() function computes the inverse hyperbolic sine of the real argument

SPECIAL VALUES

asinh(±0) returns ±0.

asinh(±infinity) returns ±infinity.

VECTOR OPERATIONS

If you need to apply the asinh() function to SIMD vectors or arrays, using the following functions provided by the Accelerate.framework may give significantly better performance:

#include <Accelerate/Accelerate.h>

vFloat vasinhf(vFloat x);
void vvasinhf(float *y, const float *x, const int *n);
void vvasinh(double *y, const double *x, const int *n);
