Syntax Remarks
the euclidean norm is computed by accumulating the sum of
squares in three different sums. the sums of squares for the
small and large components are scaled so that no overflows
occur. non-destructive underflows are permitted. underflows
and overflows do not occur in the computation of the unscaled
sum of squares for the intermediate components.
the definitions of small, intermediate and large components
depend on two constants, rdwarf and rgiant. the main
restrictions on these constants are that rdwarf**2 not
underflow and rgiant**2 not overflow. the constants
given here are suitable for every known computer.
