Press the S<>D key, (located right above "DEL"). This will shift the answer from fraction to decimal. This sounds like a pain but having both functions available can be a big plus.

If the calculator is in the MthIO mode it will always attempt to display the result as a fraction. To convert a single result to decimal, press SD. To have the result always come out in decimal (according to the selected display mode), press SHIFT MODE 2 to select the LineIO mode.

Casio fx-115 es ---- turning decimal answers into radical form


Hello,

Sorry to disappoint you but you cannot do it due to the fact that the representation of irrational (SQRT(2), ..) and transcendental (e, pi, etc.) numbers on a calculator or even a computer is approximative : a number like sqrt(2) has an infinite number of decimal digits while the number of internal digits a calculator uses to store results is limited (10, 12, 15 or even 24).
Once an irrational or a transcendental number has been evaluated numerically it generally ceases to be exact.

If you want to manipulate algebraic expressions, you need a calculator that has a CAS (computer algebra system) operating system and a symbolic algebra option.

Some exemples of calculators with a CAS are The TI nspire CAS, the HP 48 series, HP 49, HP 50, Casio ClassPad3xx, the TI 89titatium, the TI Voyager 200PLT, the TI 92 and Ti 92Plus. The ones with a fullblown keyboard might not be accepted on certain standardized test.

You may also try to get some emulators on the Internet for the HPs or the TI 8xx and play with them on the computer.

Hope that helps.

Problems with fractions on the Casio fx-115es


Hello,
To convert fractions to decimals or decimals to fractions, you use the [S<->D] key. Each time you press the key the result is displayed in the other format.
Alternatively, If you multiply or divide two integer numbers put a decimal mark at the end of one of the numbers (any one). The result will be displayed in decimal format.

Hope it helps.

When I divide answers are always given in Fractions. Can I change it to come out in decimals?


To change from Fraction display to Decimal display on the Casio fx-300ES (and probably other calculators)

1) Press the "SHIFT" button
2) Press the "MODE/SETUP" button
3) Press the "2" button
This Changes it to LINEIO (Decimal)

Doing all of the above but pressing the "1" button instead of the "2" puts it back into MATHIO mode (Fraction)

Hope this Helps

(SHIFT)(MODE/SETUP)(2) to change to decimal
