Not sure why my email got delayed so late but Conrad's way is definitely an option too. When you know that all the numbers will have the exact same number of decimals it is probably faster than my way (substring vs. a regex). My way will allow you to just grab the most significant decimal point, regardless of size, and compare on that.
Regardless, there seems to be a couple of different ways to accomplish this and I'm glad you got it working.

I haven't tried to do it much but for a simple use-case like yours I believe there are two options. 1: Use Expression Language and a Regex to move the decimal 2: (Not 100% sure this works) Use the scripting processors to write a script to do the routing For option 1 I think you can do something like this "${myAttr:replaceAll("0.(\d)(\d*)", "$1"):lt(1)}. This should "move" the decimal over one place so that you can check it against the 1. This assumes there is nothing else in that attribute. For option 2, Matt Burgess would need to weigh-in. As for NIFI-1662, it got de-prioritzed in that I got super busy with everything else I was doing for MiNiFi-0.0.1 and NiFi-1.0.0 (on-going) and it went to the back-burner. It's something I really want to get in though, along with a few other changes, because I think they open NiFi up to many new possibilities. I'd like to do it (decimals) in 1.1.0 since it wouldn't be a breaking change. Hope that helps, Joe - - - - - - Joseph Percivall linkedin.com/in/Percivall e: [email protected] On Thursday, August 11, 2016 8:16 PM, Stéphane Maarek <[email protected]> wrote: Hi, I have a flow in which I extract an attribute from json using jsonpath. That attribute happens to be a decimal number (0.123). I wanted to do a simple operation such as myAttr:lt(0.1) but obviously that won't work. What also won't work is myAttr:multiply(10):lt(1). I'm kinda stuck and I really need this logic to be working. What do you advise as a workaround? Also, I've seen there is a JIRA for this: https://issues.apache.org/jira/browse/NIFI-1662 but stuff hasn't moved much since it first appeared. Not sure if it got de-prioritized or something Congrats on the 1.0.0 beta, it looks great !! Cheers, Stephane
