The NEGPAREN
w.
d format
attempts to right-align output values. If the input value is negative,
NEGPAREN
w.
d displays the output by enclosing the value
in parentheses, if the field that you specify is wide enough. Otherwise,
it uses a minus sign to represent the negative value. If the input
value is nonnegative, NEGPAREN
w.
d displays the value with
a leading and trailing blank to ensure proper column alignment. It
reserves the last column for a close parenthesis even when the value
is positive.
