Any
numbers
containing
more
than 10digits
will
be expressed in
scientific
notation.
Also, any decimal
number
which
contains
more
than
two
digits to the right
of
the decimal
point
will
be
expressed in scientific
notation.
Atari BASIC can
only
handle floating
point
numbers
expressed in
scientific
notation
in the range between -9.99999999
E+97
and -
9.99999999
E+97
. Any decimal numbers that are closer
to
zero
than +9.99999999
E-98
or
-9.99999999
E-98
will
be
converted
to
O.
Rounding
In Atari BASIC,
floating
point
numbers can have
at
most 9
significant digits.
Any
digits
beyond
9 are replaced
with
zeros,
beginning
with
the least significant digit.
The
following
examples give the values used by Atari BASIC
for
floating
point
numbers
containing
more
than 9 digits.

Fractional
numbers
in the range
between
1 and
-1
also may
contain
a
maximum
of
nine
digits.
However,
with
numbers
in
th
is
range,
the
nine
significant digits are
counted
begin n ing
with
the
first
non-zero
digit
to
the
right
of
the decimal
point.
The
following
examples give the values used by Atari BASIC
for
floating
point
numbers
in the range
between
1 and
-1
which
contain
more
than 9 digits .
