[Solved] DMM specs question

I'm looking for a new DMM and trying to make sense of what their specs mean.
Accuracy usually described as percentage plus digits (or counts). Like:
Best AC Current Accuracy ±0.1% + 4 Digits

So wondering what 'digits' part stands for..
Watched videos on youtube but there does not seem to be a clear explanation. Apparently it's something everyone knows...

I believe it means that the least significant digit in the display can vary by 4 units, for the same current.

Ah, can vary by 4 units - that's basically (up to) +/- 4 on the last digit?
That was easy, no wonder noone bothers to explain this part making it such a mystery :smiley:
Thank you!
