About this Add-on
Allows you to work out simple arithmetic and trigonometric equations right from the address bar.
You can type something like:
- math 10+20*30/40
- math 10+20*30/40 = 25
- math 10 + cos(rad(45)) + log(10) + PI*180 / (2^4 + atan(1))
Note that (^) is a "the power of" operator, and not a bitwise-or operator.
And that (~) is the "negative" operator, so negative 2 is "~2" and not "-2".
Euler's constant (E), Natural log of 2 (LN2), Natural log of 10 (LN10), Base 2 log of E (LOG2E), Base 10 log of E (LOG10E), Pi (PI), Square root of 0.5 (SQRT1_2), Square root of 2 (SQRT2)
Supported (one argument) functions:
abs(x), acos(x), acosh(x), asin(x), asinh(x), atan(x), atanh(x), cube root (cbrt(x)), cos(x), cosh(x), radians to degrees (deg(x)), E to the power of x (exp(x)), log(x), log10(x), log2(x), degrees to radians (rad(x)), sin(x), sinh(x), square root (sqrt(x)), tan(x), tanh(x).
- If you type an equation and press the "enter" key, the result will be saved and an Address Bar icon will appear, which you can click to pull up the last 30 saved equations. The history is cleared when you close the browser.
- If you use down arrow key to select the row with the answer, the address bar will be filled with nothing but the answer, allowing you to copy and paste it.
