How to use
Use explicit * for multiplication: 2*pi. Examples: 2^3^2 = 512; -2^2 = -4; (-2)^2 = 4; sqrt(9); cbrt(-8); log(100); ln(e); 5!; 1.2e-3. Powers associate right; factorial binds before powers. sin/cos/tan use the selected angle mode; asin/acos/atan return that mode. Roots and logs support real numbers only. JavaScript floating-point arithmetic may round results; this is not arbitrary-precision calculation.
