Casio fx-115 es i get all my answers in decimal form but i want them in radical form, how?

SOURCE: When I divide, it turns the answer into a fraction. How do I get back so the answer will be a decimal?

i have this calculator too! i had this same problem, but a friend showed me how to get decimals, and having the fraction function available has proved to be EXTREMELY helpful!!!

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.

To convert a single result to decimal, press SD. To have all results come out in decimal, press SHIFT MODE 2 to select the LineIO mode.
