I’m wondering what the size of an integer is in the preferences. Mainly because I’d like to store the result of Date.now() in it, but I’m afraid it’ll cause issues if it’s too large.

From https://answers.yahoo.com/question/index?qid=20101130100955AAFylZo we see all the max values for differnt bit numbers. JS is supposed to go up to 53bit max, but we can use ctypes.UInt64 but ignoring that lets see what we can do. I created an integer pref and will now try setting it to these values below:
0 = 2^0 = 1
1 = 2^1 = 2
2 = 2^2 = 4
3 = 2^3 = 8
4 = 2^4 = 16
5 = 2^5 = 32
6 = 2^6 = 64
7 = 2^7 = 128

From trial and error it handles 32bit only, the lowest is -2147483648 and highest is 2147483647 if you try setting it outside of that, you get an error saying “The text you entered is not a number.”.

Heh, seems we passed that cutoff a long time ago. Strings it is.
