TI-BASIC:Better Code Timings

Instructions

First, write the name and model of your calculator in the table below, then use this code with an empty line in the "test code here" space to measure your loop overhead.

Add the number of iterations you used to the "iterations" column, and [time taken]/[iterations] to the "average" column. Then subtract your loop overhead from the result and list it in the "time" column.

FnOff
PlotsOff
0→Xmin
94→Xmax
-62→Ymin
0→Ymax
DispGraph //if it is a graphing command
startTmr→θ
Repeat checkTmr(θ
End
For(𝑛,1,[iterations])    //sequence variable 𝑛; note the closing parenthesis.
  //test code here
End
checkTmr(θ+1

Math Commands

Unless otherwise specified, all list/matrix elements are 1.
