When formatting doubles or BigDecimals, DigitList first formats them as a string and then parses the resultant string to extract the mantissa and the exponent. This can be done more directly. This allows removing some parsing code and removes a cached byte array.
This also facilitates potential cleanups in FloatingDecimal (removal of getChars method) but I've left that for later to minimize conflicts with other changes there. ------------- Commit messages: - unneeded comment - extract fitsIntoLong method, cleanup test - Merge branch 'openjdk:master' into digitlist-double4 - remove unused import - add fast path in BigInteger.toString for values that fit into a long - add benchmark for BigDecimal formatting - avoid parsing Changes: https://git.openjdk.org/jdk/pull/27118/files Webrev: https://webrevs.openjdk.org/?repo=jdk&pr=27118&range=00 Issue: https://bugs.openjdk.org/browse/JDK-8367324 Stats: 140 lines in 5 files changed: 51 ins; 72 del; 17 mod Patch: https://git.openjdk.org/jdk/pull/27118.diff Fetch: git fetch https://git.openjdk.org/jdk.git pull/27118/head:pull/27118 PR: https://git.openjdk.org/jdk/pull/27118
