BASIC Keywords
Specifiers
for
Numeric Fields:
#
prints the same number of digit positions
as
number
signs
(#I.
Numbers are rounded
as
necessary.
You may insert
a
decimal point
at
any position. BASIC
always prints the digits preceding the decimal point. If
there is no number, BASIC prints
a
zero.
If the number to be printed has fewer digits than posi-
tions specified, the number is right-justified (preceded
by spaces). If the number
to
be printed is larger than
the specified numeric field,
a
percent sign
(%)
is
printed in front
of
the number.
