2.53 has been released officially. Merger with [[83Plus:OS:VersionDifferences]] will happen when it happens.
  
I have recently realized that there is already an OS versions page. The two will be merged when the official release is made.

* When the ENTER key is pressed, e.g. to re-evaluate a command or to rerun a program, the last entry is automatically displayed. For example, if you type in 2+2 and press ENTER, it will return 4. If you press ENTER again, then, instead of simply displaying the answer on a new line, it displays the entry 2+2 again and the answer on new lines.

2.53 has been released officially. Merger with 83Plus:OS:VersionDifferences will happen when it happens.

To disable MathPrint: Press MODE, up, and select CLASSIC, not MATHPRINT.

Added Features

  • MathPrint is TI's own pretty printing. All the cool companies are using CamelCaps!
  • New menu Alpha+F1-F4 for use with MathPrint. All these new tokens have been moved to logical menu, except the fraction-related tokens. These are not in the symbol section of the Catalog.
  • In MathPrint, press up to scroll through previous entries, which allows basic copy and paste.
  • The WINDOW screen now has an option for setting ΔX, but not ΔY. The ability to store directly to the ΔX and ΔY tokens has always existed.
  • The TABLE screen now has a shortcut for setting ΔTbl.
  • New ZOptions under ZOOM
  • Catalog help updated. Exactly what has changed remains a mystery, as the new tokens haven't been added. Note that the old Catalog Help 83 app gives a version error when run. See http://education.ti.com/educationportal/downloadcenter/SoftwareDetail.do?website=US&tabId=1&appId=164 to download the latest version. It's interesting to note that even the splash screen still says "TI-83 Plus" and "(C) Texas Instruments 2009".
  • If an error occurred in a program, an "Error" message is displayed in place of the default "Done" message on the home screen.
  • When the ENTER key is pressed, e.g. to re-evaluate a command or to rerun a program, the last entry is automatically displayed. For example, if you type in 2+2 and press ENTER, it will return 4. If you press ENTER again, then, instead of simply displaying the answer on a new line, it displays the entry 2+2 again and the answer on new lines.

On the old OS:

2+2
      4
      4

On the new OS:

2+2
      4
2+2
      4

Whether or not this is sufficient to ensure normal operation or if disabling MathPrint too is required requires further investigation; it appears that just clearing the screen is enough for now.

  • When MathPrint is enabled, when you go to the "Y=" menu to type a function, it's displaying slowly the Y1, Y2, Y3, Y4 etc.


Bugs

This is for bugs or strange functionality. Note the above "Compatibility Issues" section; use that for issues with third-party software.

  • MathPrint Bug: When a list is displayed as a result, you can't take it back for you new entry: selecting it and pressing enter doesn't work
  • MathPrint can't handle overly complex expressions; specifically, nesting multiple levels of fractions and the pretty printed FUNC symbols will eventually cause the calculator to refuse to let you nest any further. In practice, this limit may rarely, if ever, be encountered in the classroom. If your expression is starting to require vertical scrolling, expect to encounter the old out-of-memory checkered box soon. Try to recall this expression and it won't get fully MathPrintified.
  • It is not possible to calculate the inverse of a matrix in MathPrint mode. This is because the OS converts the -1 token into the into the token sequence ^(-1), and there appears to be no way to override this behavior. This is because the OS interprets (and has always interpreted) the -1 token as a request for the inverse, whereas it thinks using ^ means you want to raise the matrix to a power, and giving it a negative number means division.
  • There are definitely stability issues with MathPrint, even without the help of assembly programs.
