power and root calculator
This page opens the scientific calculator with a power-and-root calculation already loaded. `^` raises to a power, `sqrt(x)` computes the square root, `cbrt(x)` the cube root, and a root of any index comes from the combination `x^(1/n)`.
2 raised to 10 is 1024, the classic "1 kibibyte" of computing.
12 × 12 = 144, so the square root of 144 is exactly 12.
Yes. Writing `2sin(pi/4)` works exactly like `2*sin(pi/4)`, and the same applies to cases like `2(3+4)` or `xy`. You never need to type the multiplication sign between a number and a directly adjacent variable, function, or parenthesis.
Use the expression `x^(1/n)`, where n is the root index; for example, `32^(1/5)` computes the fifth root of 32, which is 2.
Because there is no real number that, multiplied by itself, gives a negative result; the calculator refuses the calculation with an explicit message instead of silently returning "NaN".
No variables defined yet. Type something like "x = 5" and calculate to create one.

Bitwise operations work on signed 32-bit integers (from -2147483648 to 2147483647), the same semantics used by JavaScript's own bitwise operators.

All calculation happens in your browser, no expression or result is ever sent to a server. The history tape is saved locally (localStorage) on this device only; named variables exist only for the current session.
