What is PRBMath ?

PRBMath, the Paul Razvan Berg-written math library is gas-friendly and comes with default functions to handle exponentials, powers, logarithms, and square roots. Developers can create mathematical calculations in smart contracts using signed 59.18-decimal fixed-point and unsigned 60.18-decimal fixed-point numbers with up to 18 trailing decimals. Nearly 1,000 stars and over 100 forks attest to the usefulness of the library's tools.
