Both of the answers are equivalent, it is just a different way to display results.

If you are familiar with powers, this I think is called "exponent form":

10^{-3} = 1/10^{3} = 1/1000

so:

6.216216216 **x10 ^{-3}** = 6.216216216

**/10**= 6.216216216

^{3}**/1000**= 0.006216216216

Normally the fx-CG50 is limited to 10 digits, so you can end up losing some digits of accuracy depending on the way the answer is displayed. In this case it appears you lose just one digit of accuracy switching to the other form on the fx-CG50. You can see this by changing the default number format from **Norm1** to **Norm2** by doing the following:

**1)**

**2)** Scroll to the **Display** option in the menu by pressing (press "up" on the navigation button twice)

**3)** to toggle between Norm1 and Norm2 (Norm1 is the default, so Norm2 will give you the PC version)

When dealing with very small numbers **Norm1** is ideal, since any zeros in front of the result don't give you any useful information. For example:

**Norm1**

1/777777777 = 1.285714287 x10^{-9}

**Norm2**

1/777777777 = 0.00000000128

In the case of **Norm2** we only get the first 3 digits, **"128"** where for **Norm1** we get 10 digits, **"1285714287"** so depending on the answer, you can get better accuracy on the fx-CG50 by using this "exponent form".
