After much searching, I found the following (on page 376)
between: minNumber and: maxNumber
which looked promising .... but when I put in something like this:
!HotVariable between: 0.1 and: 0.2
... hoping for a true/false answer, I get the error message that HotVariables cannot perform the operation between:and:
I'd also be in business if I could find a way to combine two tests into one true/false answer...
!HotVariable gt: 0.1 & lt: 0.2
Surely there is a really easy and elegant way to do this.
