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 non-negative, 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.
