> Please review this PR and [CSR](https://bugs.openjdk.org/browse/JDK-8314607) > which clarifies the behavior of patterns in regards to the max integer > digits in j.text.DecimalFormat. > > The current specification (of `applyPattern`) states that patterns do not set > the value of max integer digits. This is incorrect, these > methods/constructors do set a value for the max integer digits. If the > pattern is in scientific notation, the max integer digits value is derived > from the pattern. Otherwise, the pattern is ignored, and the limit is set to > `Integer.MAX_VALUE`. > > See below, > > DecimalFormat df = new DecimalFormat(); > df.applyPattern("000.000E0"); > df.getMaximumIntegerDigits(); // ==> 3 > df.applyPattern("000.000"); > df.getMaximumIntegerDigits(); // ==> 2147483647 > > DecimalFormat df = new DecimalFormat("000.000"); > df.getMaximumIntegerDigits(); // ==> 2147483647 > DecimalFormat df = new DecimalFormat("000.000E0"); > df.getMaximumIntegerDigits(); // ==> 3 > > > Method descriptions should be fixed, and the relevant constructors need to > mention the behavior as well.
