Why -1 is all ones, how K-maps minimize logic, and what IEEE-754 really stores — solved step by step.
Signed integers to binary/hex at 4–32 bits with the invert-and-add-one steps shown — plus range and sign-extension notes.
Click cells (0/1/X) on a Gray-coded K-map and get the exact minimal sum-of-products — Quine–McCluskey under the hood.
Type any expression in A–D and get the exact minimal SOP — supports ', !, ·, +, ^ and parentheses.
Full truth table for any boolean expression with minterm Σm and maxterm ΠM lists — ready for your K-map.
Number ↔ float32 bit pattern with sign/exponent/mantissa split — see exactly why 0.1 + 0.2 ≠ 0.3.
Register-style bitwise math with aligned binary view — accepts decimal, 0x hex and 0b input; logical vs arithmetic shifts.
