To convert a single result from symbolic to numeric form, press the diamond key and then the ENTER key. To have all results come out in numeric form, press MODE F2, press down-arrow to move down to the Exact/Approx line, press right-arrow, and select APPROXIMATE. Press ENTER twice to save the settings and exit the mode editor.

The calculator does not show decimal when square rooting non-prime numbers. (fx-CG20)

You should feel happy that your calculator can perform some exact calculations. If you do not want the exact values you can press the SD key. You can also press SHIFT EXE rather than EXE alone.

How do i find the square root of a number on the casio scientific calculator

If, for example, you're getting the square root of 3 as the square root of 3, press the S-D button (just above the DEL) button to convert the symbolic result to a decimal result.

If you want all results to come up in decimal, press SHIFT SETUP 2 to select the LineIO mode.

Fx-115es radical notation

The calculator can show the results in radical form if it involves square roots. The 4th root of 243 is 3 times the fourth root of 3, which unfortunately is beyond the calculator's capabilities to display in radical form. Try taking the fourth root of 3 (or equivalently, the square root of the square root of 3) and you'll see the calculator display the result in decimal.

Fraction to decimal function not working,only reducing decimals not converting them to fractions when using proper 2nd function option

To force the calculator to display a result as a decimal number, try putting a decimal mark at the end of a numerator or denominator. If you are using radicals, put a decimal point at the end. Example: enter square root of 2 as SQRT(2.). Notice the decimal mark at the end of 2.

You cannot. The calculator does not have the Natural Display (math display) feature. I have heard that you can flash it with the OS of an FX-9860GII. At your own risk.

The calculator is able to display fractions and certain irrational number as radicals. However there is the twosided arrow key to

How do I find the square root of a number? and how do I enter scientific equations?

For square roots, use the square root key just to the left of the divide key. For example, 4 square-root = will give you 2.

The calculator doesn't have any way to store equations, scientific or otherwise. If you mean scientific notation, use the EE key just above the 7 key to enter exponents. For example, to enter 1.23x10^6, press 1 . 2 3 EE 6. For negative exponents, make sure to use the +- key to the right of the decimal point instead of the - key.
