uint256.xyz is a deterministic big integer calculator built specifically for blockchain developers and DeFi engineers. It handles 256-bit unsigned integer arithmetic — exactly as it behaves on EVM (Ethereum Virtual Machine) and Solana — with full support for: precise addition, subtraction, multiplication, division multiple precision contexts (e18, e9, e12) rounding operators that mirror on-chain rounding logic

I built uint256.xyz because generic calculators almost always fail when dealing with on-chain integers and fixed-point arithmetic. In smart contracts, all math is done in integers — no floats — and rounding really matters. This tool gives developers a trusted way to check calculations that match precisely how they’ll behave on EVM or Solana. Feedback from builders has already driven several quality-of-life improvements, and I’m excited to keep expanding features rooted in actual blockchain math needs.
