I can't seem to find a library that calculates mode.
the jakarta commons math is close, but the array must be in memory and no more than 100 rows.

I have an array that ranges between 20,000 and 90,000.

I found a C# version and converted it to java, but it's wrong (could be me, my conversion...). (excel's mode and PHP's mode of the same data proved that).

Ideally, I'd like a library to do it, but if someone has code they can provide that would be great too.

I agree. Here's the link:
