Implied +/- 1 only applies to rightmost non-zero digit on the left hand side of a number with no decimal point.
Technically 100 (no decimal point) is considered as +/-100.
So 110 implies +/-10, 101 +/-1
This does not apply to digits on the RHS of a decimal point, ie 100.0 does imply +/- 0.1
This is about as nerdy as this gets because nobody actually writes 100. +/-1
We had a few debates about such minutiae on that International Science panel I served on for a couple of decades.
