3x50 Glomerulus is a Web-based Casio® fx-3x50P program formatter and simulator. The program is divided into two panes. The upper pane shows the source of the program you are working on. You can change the “wroking mode” in this pane, as well as uploading/downloading the file as SPICES binary files.
The lower pane is a 16×16 matrix showing the (extended) command table of fx-3x50P. You can click on the boxes to insert a command. Of course, it is perfectly legal to type the text in the upper pane.

When you click the Preview button in the upper pane, you can obtain an HTML-formatted program preview, like the one shown on the left. If you like it, you can copy the source code on the bottom and paste it on any HTML-editting environment (e.g. a webpage). Besides, the preview interface also offer a “simulation” function, where you can test the running of the program.
Warning: Do not rely on the simulation to determine the validity of your calculator program. For instance, the program cannot parse mixed fraction correctly (e.g. 5¾ will be interpreted as (5÷3)÷4), and this program is often too accurate and too fast compared with the real machine. You have been warned.
3x50 Glomerulus is based on two SPICES libraries: The PHP-based SPICES En/Decoding library on the program formatter and the Javascript-based SPICES Emulator on the simulator. You can download the source code of both libraries in http://sourceforge.net/projects/spices/.
