I have recently noticed that the tag #BLN# ceases to return an integer ( it returns the text string "--" ) when it falls below 1 and this seems to make numerical expressions become undefined and so return 0 in the rotation or transparency fields.
When looking at watch faces on the FACER web site, the battery hands do seem rotate to point straight up when the battery level drops below 1 ( including on my watch faces). That is, if the design of the watch is such that the battery hand should point anywhere but straight up when the battery level drops below one, then this might be a problem.
I don't know if it is a real problem when the faces are on actual watches however, as I have not had a chance to look at my watch as the battery runs down to zero; I suppose in any case it would be a very short lived problem
Anyway, that is a long introduction to the question, which is, can anyone think of a way of overcoming this issue? I have tried using conditional statements but these also seem to fail when #BLN# falls below 1.
Maybe there is a way to test to see if #BLN# == "--" but I don't know how to test for a string; especially one that is a reserved operator. Is this possible do you know?
