Scientific Calculator
A scientific calculator with trigonometry, logarithms, powers, roots, constants and memory - and the expression kept on screen so you can see what you typed before you press equals.
M
DEG
What the keys do
- DEG / RAD switches what the trigonometry keys mean. It is the setting people forget, so it is shown on the screen rather than hidden in a menu.
- M+ adds what is on screen to memory, MR puts it back, MC clears it. An M appears on the screen while anything is held.
- n! is factorial, and it takes whole numbers from 0 to 170 - above that the answer is larger than a browser can hold.
- % divides by a hundred, so
50 + 10%is not a thing: write50 * 1.1. - You can type instead of clicking. Digits, operators, brackets, Enter for equals, Escape to clear and Backspace all work.
