       hypotd64(),  hypotd128(), hypotd32() - decimal Euclidean distance func‐

       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.

       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.

       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.

       If the correct value would overflow, sets to

       fabsd64(3M), sqrtd64(3M), math(5).

       These functions conform to ISO/IEC TR 24732, "Extension	for  the  pro‐
       gramming language C to support decimal floating-point arithmetic".
