Why is this variable turning into an array of 4 when I divide it?

Why is this variable turning into an array of 4 when I divide it? And only on the pattern I’m working on, not a problem with new pattern code.

Exported number variable sometimes shows as an array?

This is normal, a bit of a leftover artifact of how getVars API guesses type. Very small numbers can sometimes be mistaken for arrays. A workaround would be to e.g. add 1 to a and then it will stop glitching the UI, or use a showNumber or gauge UI control to keep an eye on it instead of the Vars Watch.
