Prefixes 0x, 0b, 0o always work. Set “Input base” to treat un-prefixed integers in that base.
Integer mode enables bitwise ops: ~ & | xor << >>. Division uses truncating integer division.
Functions: sin, cos, tan, asin, acos, atan, sqrt, log(=log10), ln, abs, floor, ceil, round, min, max.
Constants: pi, tau, e. Underscores allowed in numerals: 1_000_000.
