The

calculator

displays

all

three

decimal

places.

Press

i2nd

fj

Fl

El

to

display

1.23.

The

EL

-733A

rounds

the

number

in

the

display

to

the

specified

display

format,

however

this

rounding

only

takes

place

in

the

display.

The

number

it

stores

and

uses

in

its

calculations

contains

every

digit

(up

to

10

digits).

By

having

the

rounding

occur

only

in

the

display,

the

EL

-733A

minimizes

rounding

errors

throughout

your

calculations.

Pressing

(inI

ED

sets

the

calculator

to

display

every

digit

after

the

decimal

point,

except

for

trailing

zeros.

With

this

display

setting,

if

you

key

in

4.250000000

Ej

the

display

will

show

4.25,

whereas

if

you

key

in

4.250000001

E1

you

will

see

4.250000001.

Trailing

zeros

are

not

shown.

Digit

Grouping

Digits

in

numbers

over

one

-thousand

are

grouped

using

an

apostrophe

in

the

display

rather

than

a

comma.

For

example,

key

in

the

number

1'234'567'890.

The

reason

that

an

apostrophe

is

used

where

one

may

expect

a

comma

is

that

the

EL

-733A

is

sold

to

an

international

audience.

The

majority

of

the

world

prefers

that,

for

example,

the

number

one

-million

be

written

as

1.000.000,00

(with

a

comma

as

the

radix),

whereas

people

in

the

U.

S.

prefer

1,000,000.00.

So,

to

avoid

confusion,

SHARP

chose

a

format

that

is

easy

for

everyone

to

understand.

Very

Large

Numbers

(Scientific

Notation)

Few

people

ever

get

to

work

with

money

amounts

that

exceed

9'999'999'999.00,

but,

if

you

are

one

of

those

people

whose

assets

exceed

ten

billion,

you

may

be

interested

in

how

the

EL

-733A

handles

large

numbers

like

these.

8

Any

number

greater

than

or

equal

to

ten

billion

is

represented

in

scientific

notation.

For

example,

the

number

fifteen

billion

would

be

displayed

as

1.5000

10,

which

means

1.5

times

ten

to

the

tenth

power

(1.5

x

10").

To

key

in

large

numbers

in

scientific

notation,

key

in

the

power

of

ten

fi

rst

by

using

the

E)

key,

then

by

Clearing

The

Display

And

Correcting

Errors

Two

keys

are

provided

for

correcting

errors

in

the

display.

The

[

key

allows

you

to

backspace

incorrect

digits

from

the

number

you

are

currently

keying

in,

and

the

(ON

key

clears

the

number

in

the

display.

As

an

example,

key

in

the

number

6.22895,

then

use

Q

to

change

the

8

to

a

5.

Once

you

have

6.22595

in

the

display,

press

Coca

to

clear

the

display

back

to

zero.

Each

time

you

press

the

jGc

key,

you

clear

one

number

from

your

calculation.

For

example,

if

you

key

in

5

+

6

then

press

M

,

the

6

is

cleared

and

the

5

reappears

in

the

display.

Pressing

FM

again

clears

the

5

taking,

you

back

to

where

you

started.

The

second

function

of

the

(UM

key

is

the

clearing

function

ri

(Clear

All).

This

function

clears

all

the

registers

associated

with

a

particular

mode,

preserving

only

the

M

register.

Occasionally,

you

may

press

a

key

that

does

not

make

sense

to

the

calculator

(for

example,

try

to

divide

by

zero).

An

"E"

will

appear

in

the

lower

left

corner

of

the

display

indicating

that

an

error

occurred.

To

clear

this

error

and

continue

working,
