A classic workaround when = is not what you want in unit tests is to do the

Thank you, Jon, now I understand what the problem is.Unfortunately, in my case I can't use `number=` because the comparison is done by the unit-test word.In the following code the first test succeeds, but the second one fails: ```{ 15 } [ 10 20 middle ] unit-test{ -40.5 } [ -50 -31 middle ] unit-test``` 20.01.2017, 01:30, "Jon Harper" :Hi,you have to use number= to compare numbers with different types.http://docs.factorcode.org/content/word-number=,math.html Jon Jon On Thu, Jan 19, 2017 at 10:50 PM, Alexander Ilin  wrote:Hello!  I'm a bit confused.
