> This PR refactors the Double.toHexString method to improve its performance by > eliminating the use of StringBuilder and regex operations. The new > implementation uses a direct byte array approach to construct the hex string > representation, which avoids the overhead of StringBuilder operations and > regex pattern matching. > > Existing tests in `java/lang/Double/ToHexString.java`.
