# Euclid

> Use this tool when you need to ensure accurate and consistent mathematical calculations in your AI agent, solving problems related to data inconsistencies and unreliable outputs. Euclid provides a suite of 10 deterministic tools, including arithmetic, statistics, and unit conversion, with standardized inputs and outputs. By integrating Euclid, you can trust that the same input will always yield the same output, every time.
