Revision as of 22:27, 8 February 2010

IMPORTANT NOTE: The 2.53MP is a leaked beta. Please do not distribute it to people by calculator until TI makes the official release, slated for February 15. Use at your own risk.

I have recently realized that there is already an OS versions page. The two will be merged when the official release is made.

Added Features

  • In MP, press up to scroll through previous entries, which allows basic copy and paste.

New Tokens

  • AUTO Answer -- basic
  • CLASSIC -- basic
  • DEC Answer -- basic
  • >F<>D -- swap between fraction and decimal
  • FRAC Answer -- basic
  • logBASE( -- log to any base, logBASE(x,base
  • MATHPRINT -- basic
  • n/d - normal fraction, numerator n/d denominator
  • >n/d<>Un/D -- swap between improper and proper fractions in MP
  • randIntNoRep( -- gives a list of random integers, randIntNoRep(low,high
  • remainder( -- essentially modulo, x % y, remainder(x,y
  • summation <sigma>( -- <sigma>(expression,variable,start,end
  • Un/d -- mixed number, whole Un/d numerator n/d denominator
  • ZFrac1/2 -- delta-x,y = 1/2, graph centered
  • ZFrac1/3 -- delta-x,y = 1/3, graph centered
  • ZFrac1/4 -- delta-x,y = 1/4, graph centered
  • ZFrac1/5 -- delta-x,y = 1/5, graph centered
  • ZFrac1/8 -- delta-x,y = 1/8, graph centered
  • ZFrac1/10 -- delta-x,y = 1/10, graph centered

New Functionality

  • New ZOptions under Zoom
  • Math Print is TI's own pretty printing
  • New menu Alpha+F1-F4 for use with Math Print

Flags

  • 5, (iy+43h) controls math print. You should clear the screen if you change this flag.
  • 0, (iy+48h) controls the fraction mode
  • bits 1 and 4 of (iy+47h) are related to when the OS decides to format an answer as a fraction
  • 4, (iy+45h): set this to disable the message about shortcut menus from Press-to-Test. Not affected by Reset Defaults, though Math Print is.

Known Bugs

  • Programs using the homescreen may be very broken. Users should disable Math Print before running them, and programs should clear the screen first thing.
  • Programs that encounter an error on the graphscreen may end up with the graphscreen contents in the homescreen buffer
  • In Omnicalc, parenthesis assistant does not work properly. (Display error)
  • In Omnicalc's entries menu: Using the entries menu without MP symbols has some display issues, and when selecting an entry, it crashes.
  • In Omnicalc's entries menu: With mathprint symbols in the entries log, there are serious display issues accompanied with a dramatic crash.
  • Omnicalc's partial line clearing (always enabled) crashes or glitches when you try to use it in MP.
  • Calcutil will not run at all correctly and will crash your calculator when you turn it off and back on.
  • ld a,1 \ ld (appInfo+2),a \ bcall($50CB) no longer unlocks the flash ROM.

Known Performance Issues
