[scalding]: checking for NaN values

[SK]

I have a dataset containing a field with Double values. Some of these values are NaN. This dataset was generated by another scalding program.
 I tried to filter out the rows with NaN values using filter('val){val:Double => val != NaN). However, the compiler does not recognize NaN. I also tried comparing against  "NaN", but the compiler complains about comparing a Double with a String. What is the right way to compare with NaN values in scalding?

thanks
