NAME

       tanh(), tanhf(), tanhl(), tanhw(), tanhq() - hyperbolic tangent functions

SYNOPSIS

   HP Integrity Server Only
DESCRIPTION

       returns the hyperbolic tangent of x.

       is a version of it takes a argument and returns a result.

   Integrity Server Only
       is a version of it takes a argument and returns a result.

       is an version of it takes an argument and returns an result.

       is equivalent to on HP-UX systems.

USAGE

       To use these functions, compile either with the default option or with the and the options.

       To use (for Integrity servers) or compile also with the option.

       To use any of these functions, make sure your program includes and link in the math library by specifying on the compiler or linker command
       line.
