The actual formula expression calculator.
A fully featured scientific calculator which looks and operates like the real thing.
It is made for General engineering and field use.
**Everytime touch the answer, answer type is changed.(real-root-fraction)
1. The natural formula expression.
2.Display the results as square root if possible.
- Display root, fraction and real number : menu key -> Calculator setting -> Display result.
- Display real number only : menu key -> Calculator setting -> Display result.
3. Unit conversion.
4. Move the cursor by the touch.
5. Use and saving of functions and variables.
6. Fraction and mixed fraction feature.
