Ahhh, I think I see the misunderstanding. I'm going to take a guess that you're native language is not English?
000001 = zeros in front of 1
1000000 = zeros behind 1
Confusing, hmm.
000001 = 1 with 5 leading zeros.
100000 = 1 with 5 trailing zeros.
Here, 01, 0 comes before the 1, therefore we say 1 with a 0 behind it. Math is a universal language though, trying to change it's terms will confuse people.
Anyways, I have got my own mirror-verse to deal with. Thanks for talking with machine language with humans.😉
