NAME            hypot -- calculate hypotenuse



SYNOPSIS        (A in fr0)

                (B in fr0)

                jsr     r5,hypot



DESCRIPTION     The square root of fr0*fr0 + fr1*fr1 is returned

                in fr0.  The calculation is done in such a way

                that overflow will not occur unless the answer is

                not representable in floating point.



                The floating point simulator should be active in

                either single or double mode.

                sented.
