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.

STANDARDS CONFORMANCE
