If the result is already calculated and displayed, press the
[S<=>D] key It will convert a fraction or radical to decimal. This
is always possible. If the result is decimal it may be converted to a
fraction or a radical (Not always possible).
If the expression to be evaluated is still in the command line and you have not pressed the [=] key, you can force the result to be displayed in decimal format by pressing [SHIFT][=] instead of just [=].
More permanently. If you do n o care for fractions and radicals, set the Input/Output mode to LineIO. To do do press [SHIFT][MODE] to access the (SETUP) screen and select [2:LineIO]

Is there a PDF with the Statistical procedures for this product? I bought my Casio FX-115 used (second hand). No instructions. I need help using the Statistical functions for my Stats classes:

I am only looking for a plausible cause of the error, because I do not believe your calculator can make such a mistake. I think you accidentally activated the Exponential display format and did not pay attention to the small, raised -03 that came at the end of the number displayed. It is a common mistake for those not very familiar with Scientific or exponential notation.
Let us try to reset your calculator to the normal (floating point) format.
Press the [MODE] key a number of times until you reach a screen that has FIX, SCI, NORM and under each one a number (FIX 1, SCI 2), Norm 3). To have the number of decimal place you gave in your result (4 decimal digits), you press 1 to select Fix then 4.
Be aware that scientific calculators usually stop displaying results in floating point format ( 0.0000045 ) if the number is smaller then 0.001. So basically, 0.00099 will be displayed as 9.90-04, -04 being raised above the level, and in smaller size.
Hope it helps.
