NAME
       erfd64(), erfd128(), erfd32(), erfcd64(), erfcd128(), erfcd32() - error functions and complementary error functions

SYNOPSIS
DESCRIPTION
       returns the error function of x, defined as:

       returns	the  complementary  value, 1 - It prevents the extreme loss of relative accuracy if is called for a large x and the result is sub-
       tracted from 1.	(For example, for x=5, eleven decimal places are lost.)

       and are versions of and they take a argument and return a result.

       and are versions of and they take a argument and return 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
       returns 1.

       If x

       If x is +infinity, returns +0.

       If x is -infinity, returns 2.

       If x is NaN, these functions return NaN.

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

       These functions raise the inexact exception whenever a rounded result does not equal the mathematical result.

ERRORS
       No errors are defined.
