NAME
       tgammad64(), tgammad128(), tgammad32() - decimal true gamma functions

SYNOPSIS
DESCRIPTION
       The function computes the true gamma function of x.

       In contrast, the function computes the log of gamma.

       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.

       For more information, see the at the following site:

RETURN VALUE
       If x and raises the divide-by-zero exception.

       If x is a negative integer, returns NaN and raises the invalid exception.

       If x equals -infinity, returns NaN and raises the invalid exception.

       If x equals +infinity returns +infinity.

       If x is NaN, returns NaN.

       returns	the  properly signed infinity (or, in some non-default rounding direction modes, the properly signed maximum-magnitude finite num-
       ber) in lieu of a value whose magnitude is too large, and raises the overflow and inexact exceptions.

       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
       If x is a negative integer, sets to

       If x sets to

       If the correct value would overflow, sets to
