Fixed-Point Math Library for soroban smart contracts with advanced math and high precision

Products & Services

Product: SorobanMath Library

What the Product Is: The SorobanMath library is a comprehensive fixed-point math library designed specifically for the Soroban smart contract platform on the Stellar network. It provides developers with a set of powerful mathematical functions and precise arithmetic operations, enabling them to perform complex financial calculations with minimal precision loss.

Problems It Solves and Benefits: - Precision Loss Mitigation: The primary problem solved by SorobanMath is the precision loss inherent in Soroban's 7/9-decimal limit (not a hard limit necessarily) due to the max token balance being limited by the i128 type in Rust. So whenever an output for arithmetic operations is finished, I want to save the result of the arithmetic operations in such a way so that I don't compromise on the precision, even if it means I use more than one i128 type to save the outcome of the arithmetic operations and the rounding of the output is avoided along with a good enough precision. - Enhanced Development: It simplifies development for developers building on Soroban by providing an ergonomic API for precise mathematical operations. - Applicability: It benefits developers particularly who develop DeFi Protocols on Soroban requiring high-precision in the mathematical operations.

How It Works and How It Uses Stellar/Soroban: - SorobanMath extends the precision of fixed-point arithmetic calculations to minimize precision loss. - The library includes functions for arithmetic operations, logarithms, exponentiation, power, and more. - It will be a no_std library, something which does not use the Rust standard library, so it is directly usable in any smart contract application in the Soroban ecosystem.

In summary, SorobanMath is a specialized library designed to tackle precision challenges in Soroban, providing developers with advanced mathematical capabilities.
