| Notes: |
Not entirely sure how to classify this, it’s not quite a
scientific calculator but it’s not a basic calculator either
because it has squares, reciprocals, roots and π.
This calculator as a fluorescent display but operates upon a single AA battery. Next to the four basic functions it has a memory, percentages, and some scientific functions. It also has a "π"-key but lacks the trigonometric functions. The constant π however can still be very useful for calculations upon circles and spheres and their derivatives. |
