83 and 68k Did You Know

Did you know…

…that you can get the number of digits of a number N to the left of the decimal point by using the formula 1+int(log(N)? (edit)

…that the smallest way to implement the distance formula is by using the R►Pr( command? (edit)

…that you can use the % symbol or sub( with one argument as a smaller replacement for multiplying by .01? (edit)

…that you can get rid of the run indicator on the TI-83/84/+/SE by using Text(-1,0,90," " on the graph screen and Output(1,16," " on the home screen? (edit)

…that you can run your TI-Basic program from an assembly shell by placing a colon (":") as the first line of your program? (edit)

…that you can store to the list element one past the last element to add it to the end? (edit)

…that the finance variables are the fastest variables to use, even faster than Ans? (edit)

…that the String►Equ( command is completely useless, and you can store a string into one of the equation variables just using the → (store) operator? (edit)

…that the fastest way to check for a whole number is the command not(fPart(? (edit)

…that you can compress a list of related numbers by combining them into integer and fraction parts? (edit)

…that the majority of the graphics commands are dependent upon the window dimensions, so you should always use a friendly graphing window to ensure everything shows up as you intended? (edit)

…that you can make subprograms that are contained inside the program itself, so that they can be called by the program whenever needed? (edit)

…that you can use SetUpEditor to UnArchive a list, but at the same time create the list if it doesn't exist? (edit)

…that you can get away with not having a colon or a new line after DelVar? (edit)

…that you can scroll the Pause command's optional argument to see it in its entirety? (edit)

…that the smallest (though not the fastest) way to shade the entire graph screen is Shade(Ymin,Ymax)? (edit)

…that pressing alpha in the program editor followed by up or down, you will scroll a whole page of program code? (edit)

…that pressing [2nd] [RIGHT] in the program editor will take you to the end of your current line, and [2nd] [LEFT] will take you to the beginning of that line? (edit)

…that TI added several new TI-Basic commands to the newer TI-84+/SE calculators? (edit)

…that you can use -E99 and E99 to represent -∞ and +∞ in many calculations? (edit)
