simply
a

way of
expressing

Internally,
the
mantissa
of a
non-zero
number
is
a
13-digit
nUmber
between

or,
in
case
of
a
negative
number,
between
-1

During
printout
the
mantissa
is
rounded
to
12
digits.

3 REGISTERS
The
1155
has
two
working
registers
in
which
numbers
are
stored
and
arithmetic
is
performed.

example
illustrates
the

Both
registers
are
set
to
zero.
When a
number
is
keyed
in,
it
is
placed
in
L.
ENTER
terminates
the
entry
of a
number
and
causes
it
to
be
printed.
When a new
number
is
entered
in
L,
the
previous
number
is
bumped
up
into U.
The
number
that
was
in
L
is
added to
the
number
that
was
in
U and
the
result
is
put
into L.
Then
U
is
cleared
to
zero.
Print
the
number
that
is
in
L.
End
of
program.*
*A
program
is
a
sequence
of
keystrokes
to
solve a
problem.
The

program
is
executed
manually.
