and
the
principles
of scientific
notation.
Most
users
are familiar with
the
concept of
scientific
notation.
Basically it is
a method
used to represent
extremely large
or extremely
small numbers.
A
number
in scientific
notation
has two
parts;
the number itself
followed
by
a
power
of l0 which
designates where
the
decimal
point
should
be. A
positive power,
such
as l0n
means the decimal
point
is to
be
moved n
places
to the
right;a negative
power
indicates
that the
decimal
point
is
to be moved
r.t
places
to
the left. Thus,
8.67 X l0a
in
scientific
notation
represents
the number
86700;
8.67 X l0
a
represents
the num-
ber.000867.
Therefore,
these
two
programs
are
quite
useÍul
when we
wish to
perform
calculations
on extremely
large or
extremely small num-
bers. For
instance, if we wish
to calculate

ever, if we use Xn

by following the

we will
be able to determine

The display reads
5. 193500110.
The first
five
places
of the display
contains the numberi
the last
five
places
contain
the
power
of l0;
and
the sign indicates the
sign of
power
of

Thus, 986.536-.s
