Somewhere, during a conversion in Rust 众, a Rust telegram group with people mainly from China (Taiwan have a separate group rust.tw).Someone mentioned that it may be faster to get the … TīmeklisSo for non-demanding applications taking the modulo of a random u64 might work. (And taking the modulo of n + 128 bits can be cryptographic-grade.) • if you care a bit, convert to float, scale appropriately, convert to int (using banker's rounding) This is trickier than it sounds. Floating point is complicated.
