| Mar 6, 2017 at 13:58 | comment | added | O. R. Mapper | @SPavel: No, it doesn't; I just listed "diameter" and "average" as the two (presumeably) commonly established uses of the symbol. But then, maybe I was indeed misled by the apparent language-neutrality of the symbol, and its commonly known meanings are not as language-independent as I thought. | |
| Mar 6, 2017 at 13:42 | comment | added | SPavel | @o.r.mapper Not according to my testing. "Crossed out - oh it's empty" is most people's thought process. Diameter in this context doesn't even make sense. | |
| Mar 6, 2017 at 10:08 | comment | added | O. R. Mapper | @SPavel: "I'm less interested in making an interface for math enthusiasts"; "The symbol for empty value is easy - ∅." - to interpret that symbol as "empty", you already have to be quite a math enthusiast. To anyone else, the circle with a slash means either "diameter" or "average". | |

| Mar 4, 2017 at 2:16 | comment | added | SPavel | @BrettFromLA I'm less interested in making an interface for math enthusiasts, and more interested in making an interface with broad appeal. I don't care if it's "technically" correct as long as people get it. | |
| Mar 4, 2017 at 2:12 | comment | added | SPavel | @Alvaro "Empty" is not a value, but the absence of value (null). It's not the same thing as an empty box, because an empty box is "" - a string of length 0. Rather than trying to explain to users what "null" is we decided to go with this. | |
| Mar 4, 2017 at 0:39 | comment | added | Alvaro | I am a bit confused with the premise of the question. The center dropdown compares left with right (equal, greater, etc.), but the empty non-empty doesn't compare left with right, but it is right itself. So an example would be: $variable = empty; $variable ≠ empty; no? | |
