Omnicalc is a TI-83+/84+/SE assembly application created by Michael Vincent of Detached Solutions, and it modifies your calculator to provide additional TI-Basic functions. It works by installing a parser hook which will intercept any real( command requests (although originally it actually had its own set of custom commands that it created and used). This is the same thing that xLIB does, which means that the applications could conflict when both are installed.

Some of Omnicalc's TI-Basic features include:

  • Base conversion for a variety of number bases
  • Built-in support for several common math constants
  • Factoring a number into its prime parts
  • Improved linking support sending/receiving bytes
  • Sprites using parts of the picture variables

Besides the TI-Basic related features, Omnicalc also includes several other valuable features: a custom menu for placing common commands and functions, parentheses assistant for help entering in math expressions, protection for preventing people from messing with your calculator's memory, a thousands separators that inserts commas after every 3 digits of a number (for example, 1000000 would appear as 1,000,000), and a virtual calculator that allows you to switch back and forth between two calculators.


Unfortunately, there isn't a whole lot of documentation that has been created for Omnicalc. The main piece of documentation thas has been created so far is the TI-Basic Greyscale tutorial by Kevin Ouellet (DJ Omnimaga). This tutorial explains how to use Omnicalc together with xLIB to create greyscale sprites for use in games, although the version of xLIB that is referenced in the tutorial was just a regular assembly program. We hopefully can create some more documentation at some point in the future.
