Compute an inverse hyperbolic tangent
#include <math.h> double atanh( double x ); float atanhf( float x ); long double atanhl( long double x );
libm
Use the -l m option to qcc to link against this library.
These functions compute the inverse hyperbolic tangent (specified in radians) of x.
The inverse hyperbolic tangent of x.
#include <stdio.h> #include <math.h> #include <stdlib.h> int main( void ) { printf( "%f\n", atanh( 0.5 ) ); return EXIT_SUCCESS; }
produces the output:
0.549306
