Is b a defined symbol? (a=b are allowed, but a=c is a undefined symbol)

Hi,

I just wondered why a=b are handled well without a error thrown from mathjs. Where a=c complains about c are a undefined symbol.

But; why are b a defined symbol in the first place?

Here's a simple recreation from Math Nodepad:

I noticed this while integrated Mathjs into a solution, and wondered why a=b is allowed in the first place.

The b is the unit bits, see https://mathjs.org/docs/datatypes/units.html#reference

Oh, I see. Thanks. I actually checked the units page, but must have been overlooking the Binary > bits. Thanks!
