One-half addresses

[woodpeck]

(I received the following by email)

Is there a way to tag house numbers of the type "1263 1/2 Wellington Street West" so that the error checker does not flag as error. That's to be read as "1263 and a half". The house numbers go:

...
1261
1263
1263 ½
1265
1267
...

Question: do you also have 1/4 and 3/4 or is 1/2 the only fraction?

Answer: no, i have not seen those in my area. For places where more addresses are needed here, the sequence is like:
...
1261
1263A
1263B
1263C
1265
1267
...

If the question is if I've seen addresses with fractions in them then the answer is that I have and I've seen addresses with 1/2 and I've seen addresses with 1/3 and 2/3. This can happen when a new house was built between two already existing ones and it can happen with houses that were split up into apartments. I've also seen addresses that end in letters.

This should be partially fixed by #112 which accepts 13 1/2 and 13 1/2a as valid but 13 ½ and 13 ½a as invalid.
