The Fix command puts the calculator in fixed-point display mode: all numbers will be displayed with a fixed number of digits (0-9) after the decimal, depending on the argument of Fix. This could be useful if you're trying to display potentially fractional numbers in a limited amount of space.
A note on more technical aspects: first, if more digits are available than are displayed, the calculator will round off the displayed number (but not its stored value), so 3.97 will be displayed as 4 in Fix 1 mode. Second, the Fix command can't force more than 10 significant digits to be displayed, so something like 123456789.1 will only display one decimal digit even in Fix 9 mode.
Finally, note that the Float and Fix commands only change the way numbers are displayed: they are saved in the same way in each case. Even if you're in Fix 0 mode, the calculations are not done using integers, and in general the calculations are still done using floating-point numbers no matter the number mode. The one exception is with regressions: if you store a regression to an equation in Fix N mode, it will truncate the numbers involved before storing them to the equation, and as a result, the equation will be different.
