ASINH(3) BSD Library Functions Manual ASINH(3)NAMEasinh, asinhf, asinhl -- inverse hyperbolic sine functionsLIBRARYMath Library (libm, -lm)SYNOPSIS#include <math.h> double asinh(double x); float asinhf(float x); long double asinhl(long double x);DESCRIPTIONThe asinh(), asinhf(), and asinhl() functions compute the inverse hyperbolic sine of the real argument x. For a discussion of error due to roundoff, see math(3).RETURN VALUESThese functions return the inverse hyperbolic sine of x.SEE ALSOacosh(3), atanh(3), exp(3), math(3)HISTORYThe asinh(), asinhf(), and asinhl() functions appeared in 4.3BSD, FreeBSD 2.0, and FreeBSD 10.0, respectively.BSDJune 9, 2013 BSD
