Dividing a number into individual digits

Ruby

Here’s a simple question: What’s an effecient way to get the digits of
a number. For instance, if I have the number 37, how can I get “3” and
“7”?

I’m not sure about the efficiency but this can do:
number.to_s.split(//)
Ex: 1464002.to_s.split(//) => [“1”, “4”, “6”, “4”, “0”, “0”, “2”]

Otherwise, you may need to derive a method of your own. :slight_smile:

An inability to use the right search phrase? I had looked, but nothing
relevant came up. Thanks for letting me know about this other thread,
though. Just found it, and it answers the question nicely.

One alternative to split could be unpack

s = “12345” * 2000

s.unpack(‘C*’).each {|d| printf(“%c\n”, d)}

note that s contains ascii values for each digit obtained ( ‘0’ =>
48, …, ‘9’ => 57 )
