Nothing that I asked in this post can be found in the Manual. I asked for a formula or for a built in expression. It wasn't in the manual so I wasn't sure, plus sometimes someone doesn't know how to look up what they don't know. When rounding 5.5 is in the middle and can technically be rounded up or down. Was asking if Ceil and Floor was hard limit or not. 5.9 and 5.9999 are different. One has 10% missing while the other has .0001% missing.
Sorry for the quite useless input, but rounding 5.5 will give you 6 for equity purpose
5.0;5.1;5.2;5.3;5.4 gives 5 after rounding
5.5;5.6;5.7;5.8.5.9 gives 6 after rounding
also I think int gets the integer part of a number, which is different from floor for negative numbers.
also, you shouldn't really use int on strings, it works in the case you described but this is more an "thing that happens" rather than a feature
