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);

SEE ALSO
     acosh(3), atanh(3), exp(3), math(3)

STANDARDS
     The asinh() function conforms to ISO/IEC 9899:2011.
