Question:
All i want to do is match a number between 2-16, spanning 1 digit to 2 digits
according to http://www.regular-expressions.info/numericranges.html, they have examples for 1 or 2 digit ranges, but not something that spans both..if that makes sense.
The regex [0-9] matches single-digit numbers 0 to 9. [1-9][0-9] matches double-digit numbers 10 to 99.
Something like "^[2-9][1-6]$" matches 21 or even 96 lol. Any help would be appreciated.
Solution:1
^([2-9]|1[0-6])$
will match either a single digit between 2 and 9 inclusive, or a 1 followed by a digit between 0 and 6, inclusive.
Solution:2
With delimiters (out of habit): /^([2-9]|1[0-6])$/
The regex itself is just: ^([2-9]|1[0-6])$
Solution:3
^([2-9]|1[0-6])$
(Edit: Removed quotes for clarification.)
Solution:4
(^[2-9]$|^1[0-6]$)
By specifying start and stop for each set of numbers you are looking for your regex won't also return 36, 46, ... and so on. I tried the above solution and found that this works best for staying within the range of 2-16.
