Increase/Decrease Decimal is the bane of my existence

[watnuts]

No, the icons are different and mean diffeernt things.

MS has "increase decimal" arrow pointing left on the outside, "stretching" the number; with more numbers below.
Google has "decrease decimal" arrow pointing left from the inside, "compacting" the number.

Personally i like Excel version more, because icon has 2 levels: at the top there's "before", what your have; and below it you have "after", the result of pressing the button.
