ExpressionEvaluator isn't handling NaN correctly
------------------------------------------------
Key: JANINO-126
URL:
http://jira.codehaus.org/browse/JANINO-126 Project: Janino
Issue Type: Bug
Affects Versions: 2.5.14, 2.5.13, 2.5.12, 2.5.15
Environment: Windows jdk5
Reporter: mark zeldis
Assignee: Arno Unkrig
NaN is not working within the ExpressionEvaluator. All evaluations involving NaN should be false. Here is an example:
import org.codehaus.janino.*;
public class TestTest {
public static void main(String args[]){
try {
ExpressionEvaluator advancedFilter= new ExpressionEvaluator(
"x>5", // expression
Boolean.class, // expressionType
new String[]{"x"}, // parameterNames
new Class[]{Double.class} // parameterTypes
);
System.err.println(advancedFilter.evaluate(new Double[]{Double.NaN}));
System.err.println(Double.NaN>5);
}
catch (Exception e) {
e.printStackTrace();
}
}
}
