TI-84 Plus CE Update: OS
5.2
There is a new OS for the TI-84
Plus CE: 5.2.1.0042. Many thanks to Rich Grubbs who emailed me about this recent OS update.

According to Texas Instruments, this update corrects issues found
in the Sequence Mode editor.
This is an extension of OS 5.2, which added new functions,
found in the catalog:
eval(: Evaluates an expression and returns the answer
in a string format. The expression must result in a real result.
Example:
eval(6*√11)→Str1 stores 19.899749 in Str1
eval(6*√-11)→Str1 returns an
Error. This happens even when the
complex mode (a+bi or re^(θi)) is selected
toString(: Similar to eval( but handles matrices, lists,
and complex numbers.
What is nice that the Prgm, I/O
command lists adds eval(, expr(, toString(, and String>Equ( to the menu, so
no more scrolling through the catalog during programming.
Wait: Pauses the program for a specified amount of
seconds. Wait is found in the Prgrm, CTL
menu under option A. As a consequence,
IS>(, DS<(, etc, are pushed one command below.
Example Program: Program TST4224
For(I,1,5)
ClrHome
Output(1,1,I)
Wait 1
End
I plan to update the TIMER and STOPWTCH programs in short order.
invNorm(: This command has been updated. You can use RIGHT, CENTER, or LEFT to
determine which part of the normal curve is affected.
Example: (With σ = 1 and μ = 0)
invNorm(.85, LEFT) returns
1.03643338
invNorm(.85, CENTER) returns
{-1.439531471, 1.439531471}
invNorm(.85, RIGHT) returns
-1.03643338
Caution: LEFT, CENTER, and RIGHT are not available for
invT( or invBinom(.
Sequences: The sequence editor now allows up to two initial
conditions, double deep recurring sequences.
The example sequence shown is
u(n+2) = .5*u(n) + 2*u(n+1), with u(1) = 0, u(2) = 0.5 (5 points are plotted)
Apps for the Vernier EasyData,
TI-Innovator, TI Test Guard, SmartPad, and language localizations are
updated.

Caution:
When updating, make sure you backup up and/or save your files
because the update will erase everything stored in RAM.
