    Command:

    atanh

    
    
    

    SYNOPSIS

           #include <math.h>
    
           double atanh(double x);
           float atanhf(float x);
           long double atanhl(long double x);
    
           Link with -lm.
    
       Feature Test Macro Requirements for glibc (see feature_test_macros(7)):
    
           atanh():
               _BSD_SOURCE || _SVID_SOURCE || _XOPEN_SOURCE >= 500 ||
               _XOPEN_SOURCE && _XOPEN_SOURCE_EXTENDED || _ISOC99_SOURCE ||
               _POSIX_C_SOURCE >= 200112L;
               or cc -std=c99
           atanhf(), atanhl():
               _BSD_SOURCE || _SVID_SOURCE || _XOPEN_SOURCE >= 600 ||
               _ISOC99_SOURCE || _POSIX_C_SOURCE >= 200112L;
               or cc -std=c99
    
    
    

    DESCRIPTION

           The atanh() function calculates the inverse hyperbolic  tangent  of  x;
           that is the value whose hyperbolic tangent is x.
    
    
    

    RETURN VALUE

           On success, these functions return the inverse hyperbolic tangent of x.
    
           If x is a NaN, a NaN is returned.
    
           If x is +0 (-0), +0 (-0) is returned.
    
           If x is +1 or -1,  a  pole  error  occurs,  and  the  functions  return
           HUGE_VAL,  HUGE_VALF,  or  HUGE_VALL, respectively, with the mathemati-
           cally correct sign.
    
           If the absolute value of x is greater than 1, a  domain  error  occurs,
           and a NaN is returned.
    
    
    

    ERRORS

           See  math_error(7) for information on how to determine whether an error
           has occurred when calling these functions.
    
           The following errors can occur:
    
           Domain error: x less than -1 or greater than +1
                  errno is set  to  EDOM.   An  invalid  floating-point  exception
                  (FE_INVALID) is raised.
    
           Pole error: x is +1 or -1
                  errno  is set to ERANGE (but see BUGS).  A divide-by-zero float-
                  ing-point exception (FE_DIVBYZERO) is raised.
