Percentiles as float instead of int

[Bastien Duclaux]

Hello

We’re using datamash in our production chain at many levels, and I wonder if it would be possible to add support for float percentile values, instead of int.

In particular, I would like to be able to run the following command :

datamash perc:99.9 1 < dataset

I had a look at the source code, and it seems that percentile parameters are unsigned int. Maybe it’s not too difficult to change, but I don’t know about the data mash internals :

Thanks for the great work !

Best regards
