Ruby on Rails: How do you add add zeros in front of a number if it's under 10?
- by sjsc
I'm looking to convert single digit numbers to two-digit numbers like so:
9 ==> 09
5 ==> 05
12 == 12
4 ==> 04
I figure I could put a bunch of if-else statements (if number is under 10, then do a gsub) but figure that's horrible coding. I know Rails has number_with_precision but I see that it only applies to decimal numbers. Any ideas on how to convert single-digits to two-digits?
