Are there any other combinations of a number and a suffix in French? The examples I found were only ordinal numbers.
In a completely different context, you may encounter some suffixes in street numbers, such as :
5bis, 5ter, 5quater...
Typically, these cases happen for formerly bigger properties that were divided later:
| --- 3 --- | --- --- 5 --- --- | --- 7 --- |
| --- 3 --- | -- 5 -- | -5bis- | --- 7 --- |
If you want to know more about it, you can follow this link (fr).
There is the same principle for quantities, with "aine" for sufix :
douzaine (dozen) : 12aine , quinzaine (fifteen or so) 15aine , and all tens : 10aine, 20aine, 30aine...
100aine is the only hundred to be written this way
Edit : soixante-dizaine (70aine), quatre-vingtaine (80aine) and quatre-vingt-dizaine (90aine) are very rarely used.
