NAME
       tand64(), tand128(), tand32() - decimal tangent functions

SYNOPSIS
DESCRIPTION
       returns the tangent of x (x specified in radians).

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

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

       These  math  functions  are supported for HP-UX 11i Version 3 September
       2008 Update and forward.

USAGE
       To use any of these functions, compile with the option.

       Make sure your program defines and then includes

       Link in the math library by specifying or on the linking command line.

RETURN VALUE
       If x returns NaN and raises the invalid exception.

       If x is NaN, returns NaN.

       raises the underflow exception whenever a result is  tiny  (essentially
       subnormal or zero) and inexact.

       raises  the  inexact exception whenever a rounded result does not equal
       the mathematical result.

ERRORS
       No errors are defined.
