Resolution: Duplicate
> java.text.DecimalFormat does not parse infinite values correctly
> ----------------------------------------------------------------
>
> Key: HARMONY-107
> URL: http://issues.apache.org/jira/browse/HARMONY-107
> Project: Harmony
> Type: Bug
> Components: Classlib
> Reporter: Richard Liang
>
> In Java 1.4.2 Spec of java.text.DecimalFormat.parse(String, ParsePosition), it's said:
> Values that cannot fit into a Long are returned as Doubles. This includes values with a fractional part, infinite values, NaN, and the value -0.0.
> The test cases will fail if excuting under Harmony and pass on RI:
> // Test whether DecimalFormat can parse Positive infinity correctly
> public void testParseInfinityBigDecimalFalse() {
> DecimalFormat format = (DecimalFormat) DecimalFormat.getInstance();
> DecimalFormatSymbols symbols = new DecimalFormatSymbols();
> Number number = format.parse(symbols.getInfinity(), new ParsePosition(0));
> assertTrue(number instanceof Double);
> assertTrue(Double.isInfinite(number.doubleValue()));
> }
> // Test whether DecimalFormat can parse Negative infinity correctly
> public void testParseMinusInfinityBigDecimalFalse() {
> DecimalFormat format = (DecimalFormat) DecimalFormat.getInstance();
> DecimalFormatSymbols symbols = new DecimalFormatSymbols();
> Number number = format.parse("-" + symbols.getInfinity(),
> new ParsePosition(0));
> assertTrue(number instanceof Double);
> assertTrue(Double.isInfinite(number.doubleValue()));
> }
