I’ve noticed that there are two different tags for rounding numbers to an approximate value.
- rounding has 3870 questions and already has the synonym round
- number-rounding has 126 questions.
Their tag excerpts clearly describe the same thing:
Rounding a numerical value means replacing it by another value that is approximately equal but has a shorter, simpler, or more explicit representation.
Number rounding refers to the process of rounding numbers to a certain digit place (i.e. 1.45 rounded to the nearest tenth is 1.5).
Therefore, I suggest these two tags should be merged, with rounding being the master tag.
It looks like the synonym has finally been proposed after a long time.
