hypot(3M)							     hypot(3M)

NAME
       hypotf(), hypotl(), hypotw(), hypotq() - Euclidean distance functions

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

   Integrity Server Only
       is a version of it takes arguments and returns a result.

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

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

       is equivalent to on HP-UX systems.

USAGE
       To use any of these functions, compile either with the  default	option
       or with the and options.

       To use (for Integrity servers) or compile also with the option.

       Make  sure your program includes Link in the math library by specifying
       on the compiler or linker command line.

RETURN VALUE
       and are equivalent.

       is equivalent to

       returns +Inf, even if y is a NaN.

       If both arguments are NaNs, then returns a NaN.

       returns infinity in lieu of a value whose magnitude is too  large,  and
       raises the overflow and inexact exceptions.

       raises  the  underflow and inexact exceptions whenever a result is tiny
       (essentially denormal or zero) and thereby suffers  loss	 of  accuracy,
       and may raise those exceptions if the result is merely tiny.

       raises  the  inexact exception whenever a rounded result does not equal
       the mathematical result.

ERRORS
       No errors are defined.
