NAME
       hypotd64(), hypotd128(), hypotd32() - decimal Euclidean distance functions

SYNOPSIS
DESCRIPTION
       computes the square root of the sum of the squares of x and y, without undue overflow or underflow.

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

       is a version of it takes arguments 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
       and are equivalent.

       is equivalent to

       returns +infinity, even if y is NaN.

       If one argument is NaN and the other is not returns NaN.

       returns	+infinity  (or, in some non-default rounding direction modes, the maximum finite number) 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 the correct value would overflow, sets to
