SIGNED
NUMBERS
As
shown
below, a
trailing
sign,
when
specified
in
a format statement,
either prints a
blank
for
a
positive
number
or
a
minus
(-)
for
a
negative
number.
This
form
is
sometimes
desired
by
accountants.
A
leading sign
always
prints
a plus
(+)
or a
minus
(-)
for
the sign
of
the
number.
If
no
sign
is
specified
in
the format, then
no
sign
is
printed.
This
works
essentially
like
an
absolute value
on
the
number.
