AlexCalc is a scientific calculator with LaTeX display, supporting button or plaintext input. Supports variables, complex numbers, and units. The LaTeX display makes it easy to see how your input is interpreted-- no more counting brackets! Some features: - complex number support, in rectangular or polar form (e.g. `3 + 4i` or `1 angle 90`) - variable storage (e.g. `123 -> x` then `3*x^2 - 4*x + 5 -> y`) - units in equations, and conversion (e.g. `1 inch * 3 ft to cm^2` or `sqrt(60 acre) - 100 ft`) - can enter input by button presses, typing, or copy/pasting. Button presses are all converted to plaintext input for easy copy/pasting. - equation display is simplified upon pressing enter. This means that when entering an equation, it is usually possible to look only at the LaTeX display and not the plaintext input: but when pressing enter, it will look nice. Redundant brackets are removed, including those that are needed for plaintext input (e.g. `(a + b)/(c + d)` can become "a + b" on the numerator and "c + d" on the denominator without brackets). - light/dark themes - previous input history can be accessed and edited by pressing "up" or "down" buttons. - previous inputs/vars/recently used units preserved when the app is closed - standard scientific calculator features, such as: - trigonometric functions: sin, cos, tan, arcsin, arccos, arctan - base 10 and natural logarithmic functions: log (base 10), ln (base e) - `e`, `pi` constants, and square root function - scientific notation input (e.g. `1.23E6` is 1.23 times 10^6)
