# How do i display very small exponents on the sharp 531w calculator... for example: the screen simply shows 0.0000000 for the answer 7.4*10^-14 ...i can't get answers correctly on a test or working a problem if i can't see the answer

Hello,
You have several number display formats : Normal1, Normal2, Sci, ENG
If a number is too small or too large and the calculator cannot display it with the necessary number of digits (to satisfy your of decimal digits) the calculator uses Scientific notation
7.4E-14 =7.4x10^(-14)
If you were to use the norma1 or normal2 format you will have
.0000000000000074 but your calculator displays only the first 10 places

You should learn to use and interpret results in scientific format.

Hope it helps

### Sharp el556d

Is the calculator also displaying an exponent at the far right to indicate that the number is 5.000x10^1, with a little "SCI" indicator as well?

If so, press 2ndF and [FSE] repeatedly to cycle through the various display modes.

### I cannot get the answer in decimal format. I have tried everything in the manual, and also online suggestions. Here's an example: Evaluate: (.2) with exponent of 4... the answer should be .0016,...

In the default NORM1 display mode, values whose magnitude are less than 0.01 are automatically displayed in scientific notation.

Press SHIFT MODE 8 2 to select the NORM2 display mode. In this mode, the calculator does not switch to scientific notation until the magnitude drops below 0.000000001 .

This is all described in the "Calculation Modes and Calculator Setup" section of the manual, beginning on page E-7.

### Why won't my sharp EL 531W give me the correct answer for SIN e.g SIN 30 should = 0.5 but my calculator gives me 0.453990

### My calculator will show fractions instead of decimals when doing division. How do I change that? There is a N1 displayed in the lower left corner also...I think that may be the problem

Getting Decimal Answers by Disabling WriteView on the Sharp EL-W516 Calculator

Disabling WriteView

Press 2ndF and MATH to enter SET UP. Now press 2 for EDITOR.

There are now two options: 0: W-VIEW, and 1: LINE

Press 1 for Linear display mode to disable the WriteView display, and to get decimals as your answers.

To return to the WriteView display, go through the steps above but press 0 for W-VIEW.

NOTE: It is not possible to have decimals as the default answer form when in WriteView mode.

### I have a Sharp EL-531W.All keys work except for sin cos tan hyp.

No solution, but I have the exact same problem with a Sharp EL-531W calculator. Doesn't matter whether mode is degrees, radians, etc., and resetting with button in back has no effect.

### To the power of a negative

Hello,
Use the small (-) sign sometimes labelled [(-)] or [+/-] and put the whole exponent netween parentheses 18 [y to the x] [(] [(-)] 3 [)] . On some calculators you enter the small - signe after the value of exponent,
18 [y t x] 3 (-) [Enter] should give you 1.7146E-4
In summary the small minus sign; the whole negative exponent between parentheses.
Hope it helps.

### To solve 10 raised -3, to be done with cal., answer in the display ought to be .001

The calculator has several decimal display formats: FIX, SCI, NORM and ENG.
Here are examples of calculations with different formats and how to set them.

It may be a good idea for a user to get accustomed to the scientific display format, because it is the one most calculators adopt when the result to be displayed is too large or too small--when there are not enough places on the screen to display the result.

1 billion =1000 000 000 =1 E 09 (9 zeros after 1 >> exponent 9)
1 million=1 000 000 = 1 E 06 (6 zeros after 1 >> exponent 6
1 thousand= 1000 =1 E03 (3 zeros after 1 >> exponent 3)
One= 1 = 1 E0
One tenth = 1/10 =0.1: the 1 is ONE position after the decimal mark>> exponent -01
One hundredth =1/100 =0.01 the 1 occupies the 2ND position to the right of the decimal point, exponent -02
etc.
1/1000 =0.001 = 1E-03
1/10000=0.0001=1E-04 (1 in 4th position to the right of decimal mark)
1/1000000=0.000001 = 1E-06 (1 in 6th position to the right of decimal mark)

1E-09 =0.000000001 : the 1 is in the 9th position to the right of decimal mark.

### How do i display exponents besides 2, or 3 on the sharp EL-531WH?

### Half-life exponential problem. Can't get the same answer as example

Hello,
Here is how you enter it.
[+/-]0.693/8x4[2ndF][e^x][=] result is 0.7071588193 or as you wrote 0.7071
some calculators show an error message if you enter the [+/-] (the negative of a number before the number itself).
In that case enter 0.693 then press [+/-]. the calculator should put a small - sign before the 0.
You can try
0.693[+/-][x]4[/]8[2ndF][e^x][=]

Hope it clarifies things.
