Adding 0 to beginning of a number

Rails
1

Hi

Is there a quick way to add 0 to the beginning of a number if it only
has one digit?

ie
1 should be 01
11 should stay as 11

(These int’s can be transferred to a string)

Thanks

have to be converted to a string to work…

if my_var < 10
my_var = “0” + my_var.to_s
else
my_var = my_var.to_s
end

If you need to “convert” them only for output, you should be able to use
printf/ sprintf or format… just use “%02d” as the format specifier for
the number.

sprintf “%02d”, my_var

or:

format “%02d”, my_var
