About the Mathmatical Constants Search Engine: The search engine was written as a VB6 class (DLL) that scans text files containing 2 billion decimal digits of Pi, E and the Square Root of 2. The application server is a Virtual Machine running on an Intel Core2 microarchitecture CPU and the search file itself is stored on an Intel G2 SSD. It takes less than 25 seconds to scan the entire file.
