[2.0.14] Parameterisation underflow

[JohnyDL]

I tried to place a parameter with a -1 value to compare against in a combinator and the combinator underflowed to 2.1G, pretty sure this is a bug, I'm using "* > -1" in a combinator because the value is customisable and I have other things with 0 but the -1 is customisable.

In some ways grouping (or ungrouping) different types of use of the same value would occasionally be really useful

Thanks for the report, I think this is a duplicate of 119696.
