Magnitude
The magnitude
of
a number
is
its absolute value. The
range
of
numbers permitted
in
5100 BASIC programs
is
greater than
or
equal
to
.1
E-99
and
less
than 1 E+99.
Precision
In BASIC, the precision
of
an
integer
or
fixed-point number
is
the maximum number
.
of
significant digits
it
can
contain. The precision
of
a floating-point number
is
the
number
of
significant digits
to
the
left
of
the E
(see
Floating-Point Format). The
precision
of
numbers in the 5100
is
13 digits.
Arithmetic Data Formats
Arithmetic
data
can
be
entered, displayed,
or
printed in any
of
three formats: integer,
fixed point,
or
floating point. The appropriate format
for
a given number depends
on its magnitude and the
level
of
arithmetic precision you require.
Numbers in any format
can
be
positive
or
negative. Negative numbers must
be
preceded
by
a minus sign.
When
no
sign
is
specified, a number
is
treated
as
a posi-
tive number,
so
plus
signs
are
optional.
Integer Format
Numbers
expressed
in integer format (I-format)
are
written
as
a number
of
digits
optionally preceded by a sign. Examples
of
numbers in integer format are:
o
+2
-23
2683
Fixed-Point Format
Numbers
expressed
in fixed-point format (F-format)
are
written
as
a number
of
optional digits preceded by
an
optional
sign
and followed by a decimal point. The
decimal
point
can
also
be
followed by a number
of
digits.
These
digits
are
required
if
a number
does
not
precede the decimal point. Examples
of
numbers in fixed-point
format
are:
33.
33.00
-.3
+3.56
