![]() The next two While loops simplify the surd in the numerator. The first While loop (While is better than Do, as Do must always be run once) rationalises the denominator. The inputted number is rounded to the specified number of significant figures (10 in normal mode) to account for errors accumulated when multiplying surds. The first and second Frac tests skip straight to the answer for rational numbers.

Since projects for Prizm calculators are not seen here very often, I thought I might as well post this here.I have written a program that works just like RUN mode, but gives answers in exact values, that is displaying surds (in simplest form) and fractions (rationalised) simultaneously (even for trigonometry!) Here it is, please give me your opinions, feedback. The Utilities add-in enhances your Casio Prizm calculator by providing functionality not originally found in the OS, or by providing enhanced alternatives to existing functionality.ĭownload links are after the screenshots, on the "Download" section. Really fast to start up - it's usually even faster than the built-in app Run-Mat!ĭownload g3a directly (simpler, you can even download directly to the calculator drive)ĭownload ZIP archive for the PicoC edition - Information about PicoC Weights less than 185 KiB, saving space on your Prizm's storage memory and speeding up its transfer between calculators. If you are planning on hosting Utilities on calculator software archives, please use the unmodified ZIP file which has the Read-Me and license files. ![]() Still, I would appreciate you didn't host it yourself, and just linked to the above links. It makes updating easier and also lets me count the downloads better.įor sending directly to your friends' calculators, you don't need to send the Read-Me or the license. To install, connect the Prizm calculator to the computer with a miniUSBUSB cable. ![]() On the calculator, press F1 when a pop-up appears on the screen. Wait for the USB connection to be established. When it's finished, your Prizm will appear on your computer as if it were a pendisk.Ĭopy "utilities.g3a" to the root folder of the pendisk (i.e., out of any folders but inside the pendisk) and safely remove it. Wait for the calculator to finish "updating the Main Memory". When it does, you should notice a new Menu item, with a Clock icon, called "Utilities". The first time you run Utilities you'll be presented with the tny. internet media group logo and then a screen with some important notes about the add-in. You will then be guided to adjust the clock, something you'll have to do every time you take the batteries off. Don't worry, Utilities will remind and guide you through the process.Ĭopy the new utilities.g3a over the old one. Refer to the installation instructions for more details. If you used a version of Utilities older than Beta 9, see here.Įverything should be pretty much self-explanatory - Utilities is made to dispense the Read-Me.
