Karl Yang commented on MATH-1042:
---------------------------------

I started a discussion on the 'dev' ML.
If we just add method to convert int[] to double[], when data is very large, JVM would call GC to free the memory many times in a thread, I think it's a big cost.

> Sometimes we want to find the min value, max value, percentile in a int[], but the StatUtils only support double[], we need to convert int[] to double[].
