Please review this PR which updates the Scientific Notation section of Decimal Format. It aims to resolve [JDK-8159023](https://bugs.openjdk.org/browse/JDK-8159023) as well as [JDK-6282188](https://bugs.openjdk.org/browse/JDK-6282188).
**Scientific Notation** in Decimal Format contains the definition for a scientific notation formatted number's mantissa as such: _The number of significant digits in the mantissa is the sum of the minimum integer and maximum fraction digits, and is unaffected by the maximum integer digits. For example, 12345 formatted with "##0.##E0" is "12.3E3"._ Both the definition and example are incorrect, as the actual result is "12.E345". The following example data show that scientific notation formatted numbers do not adhere to that definition. As, according to the definition, the following numbers should have 3 significant digits, but in reality, they have up to 5. 123 formatted by ##0.#E0 is 123E0 1234 formatted by ##0.#E0 is 1.234E3 12345 formatted by ##0.#E0 is 12.34E3 123456 formatted by ##0.#E0 is 123.5E3 1234567 formatted by ##0.#E0 is 1.235E6 12345678 formatted by ##0.#E0 is 12.35E6 123456789 formatted by ##0.#E0 is 123.5E6 The actual definition of the mantissa, as well as examples and further context are included in this change. In addition, a test has been added that tests various patterns to numbers and ensures the format follows the new definition's mathematical expression. ------------- Commit messages: - Remove comments if they serve no purpose in the code - Add test for new definition - Add Specification Changes: https://git.openjdk.org/jdk/pull/14066/files Webrev: https://webrevs.openjdk.org/?repo=jdk&pr=14066&range=00 Issue: https://bugs.openjdk.org/browse/JDK-8159023 Stats: 158 lines in 2 files changed: 151 ins; 0 del; 7 mod Patch: https://git.openjdk.org/jdk/pull/14066.diff Fetch: git fetch https://git.openjdk.org/jdk.git pull/14066/head:pull/14066 PR: https://git.openjdk.org/jdk/pull/14066
