- Logaritamske funkcije: [LOG] (baza 10) i [LN] (prirodni logaritam).
- Funkcije potencije i korijena: [x²], [√], [xʸ], [ʸ√x].
- Factorial: [x!].
3. Funkcije pamćenja
Spremite i pozovite vrijednosti pomoću memorijskih tipki:
- [M+]: Dodaje prikazanu vrijednost u memoriju.
- [M-]: Oduzima prikazanu vrijednost iz memorije.
- [MR]: Recalls the value from memory.
- [MC]: Briše memoriju.
4. Kutne jedinice
The calculator supports Degree (DEG), Radian (RAD), and Grad (GRA) angle units. Press [NAČIN RADA] repeatedly to cycle through the angle units. The current unit is indicated on the display.
