BadComparison

Avoid equality comparisons with Double.NaN. Due to the implicit lack of representation precision when comparing floating point numbers these are likely to cause logic errors.


                  
//EqualityExpression[@Image='==']
 /PrimaryExpression/PrimaryPrefix
 /Name[@Image='Double.NaN' or @Image='Float.NaN']
                  

Example(s):


  
boolean x = (y == Double.NaN);
