[jira] Created: (HARMONY-106) java.text.DecimalFormat does not
parse infinite values correctly
java.text.DecimalFormat does not parse infinite values correctly
----------------------------------------------------------------
Key: HARMONY-106
URL: http://issues.apache.org/jira/browse/HARMONY-106
Project: Harmony
Type: Bug
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()));
}
