- √ - Square roots. The P key will calculate the square root of a gven number.
- GT - Memory calculation. The P key will display the "Grand Total" of all calculations so far. Every time the = key is pressed after the last time the AC key was pressed, the result is added to this "Grand Total". The "Grand Total" memory works independent from the calculators regular memory.
- rem - Remainder This setting will change the operation of divisions. Divisions are performed as with integer results, and the P key will show the remainder. Thus, when performing 6 / 4, the result will be 1, and the P key will yield 2.
- Ab/c - Fractional calculation. This will change the P key into the "fraction" key present on many CASIO calculators, and will let the calculator operate on fractions.
- hms - Time calculation. This will change the P key into the "hours minutes seconds" key present on many CASIO calculators.
- SD - Standard deviation. This will change some keys on the calculator. The = key will act as a Σ+ operator. The memory keys will perform the statistical functions displayed above them. The normal memory functions are unavailable in this mode. The P key will calculate the standard deviation.
Even though this calculator has some sophisticated scientific functions it has a quite common bug in that this calculator has no problems with negative square roots and thinks √-9 = -3.
