At the time of SQLite4, I wrote to him asking why he had dismissed IEEE 754 as a storage format in favor of a custom encoding. His answer was that he wanted comparisons to be performed using memcmp(), which IEEE 754 does not allow. There may have been other reasons (complexity, range, ...), but that one stuck with me and prompted me to start searching for order-preserving encodings.
