Aravind Rajasekaran enhanced the documentation for the Solidity RNG library in the zama-ai/fhevm repository, focusing on clarifying usage constraints to prevent common implementation errors. He specified that the upper bound for random number generation must be a power of two, reducing ambiguity for developers integrating smart contracts. Using Markdown and Solidity, Aravind updated both the documentation and code examples to reflect this requirement, ensuring consistency between guidance and implementation. The work addressed a subtle but important aspect of random number generation, demonstrating attention to detail and a methodical approach to documentation that supports more reliable and secure smart contract development.
