PRBMath is a Solidity library for advanced fixed-point arithmetic using signed SD59x18 and unsigned UD60x18 number formats with 18 decimals. It provides gas-efficient, type-safe math functions like logarithms, exponentials, powers, square roots, and overflow-safe mulDiv for smart contract development.
Use cases
- perform fixed-point math in solidity smart contracts
- compute logarithms and exponentials on-chain
- implement defi pricing and interest calculations
- safe multiplication and division without overflow in solidity
- type-safe decimal arithmetic for evm contracts
When to choose
- you need precise decimal math in solidity with 18-decimal fixed-point numbers
- you want type safety via user-defined value types
- you need gas-efficient advanced math functions like exp, ln, and sqrt on-chain
When to avoid
- you only need simple integer arithmetic
- you prefer binary fixed-point formats like ABDKMath64x64
- you are not developing for the EVM
