BadComparison


BadComparison
Avoid equality comparisons with Double.NaN - these are likely to be logic errors.
      
		
		
		    
    			This rule is defined by the following XPath expression:
    			
    			
                      
//EqualityExpression[@Image='==']
 /PrimaryExpression/PrimaryPrefix
 /Name[@Image='Double.NaN' or @Image='Float.NaN']
                  
              
  
		    
		    
	    
	    
        
        
        Example:
            
                    
  
public class Bar {
 boolean x = (y == Double.NaN);
}
