ATANH(3) BSD Library Functions Manual ATANH(3)NAMEatanh, atanhf, atanhl -- inverse hyperbolic tangent functionsLIBRARYMath Library (libm, -lm)SYNOPSIS#include <math.h> double atanh(double x); float atanhf(float x); long double atanhl(long double x);DESCRIPTIONThe atanh(), atanhf(), and atanhl() functions compute the inverse hyperbolic tangent of the real argument x. For a discussion of error due to roundoff, see math(3).RETURN VALUESThese functions return the inverse hyperbolic tangent of x if successful. If the argument has absolute value 1, a divide-by-zero exception is raised and an infinity is returned. If |x| > 1, an invalid exception is raised and an NaN is returned.SEE ALSOacosh(3), asinh(3), exp(3), fenv(3), math(3)HISTORYThe atanh(), atanhf(), and atanhl() functions appeared in 4.3BSD, FreeBSD 2.0, and FreeBSD 10.0, respectively.BSDJune 9, 2013 BSD
