Notice
that
a
string
can
contain
both
letters,
numbers
and
~ymbols.
Any
string
containing
numbers
cannot
be
used
in
a
mathematical
operation,
unless
it
is
first
converted
into
numeric
data. String
to
numeric
data
conversion
is
covered
later
in
this
chapter
.
NUMERIC
DAT
A
The
lie
can use
either
of
two
types
of
numeric
data-integers
and
floating
point
numbers.
Integers
do
not
have a
decimal
portion
while
floating
point
numbers
can have a
decimal
portion.
Applesoft
BASIC
can process
both
integers and
floating
point
numbers
while
Integer
BASIC
can
only
process integers.
Floating Decimal
Point
With
floating
decimal
point
numbers,
a
decimal
point
is
always
assumed.
Any
number
of
digits
can
be
placed
on
either
side
of
this
decimal
point.
Even
with
numbers
with
no
decimal
position,
a
decimal
point
always
is
assumed
following
the
number's
last
digit.
Floating
point
numbers
of
up
to
9
digits
can
be
used
with
Applesoft
BASIC.
For
example
,
the
following
entry
of
a
nine
digit
floating
point
number:
PRINT
.566666666
would
generate a
nine
digit
display.
If
a
10
digit
floating
point
number
was
entered:
PR
I
NT
.5666666666
the
last
digit
would
not
be
displayed and
the
number
would
be
rounded
as
follows:
