For example, cat comes before dog in the dictionary, so... puts ' cat ' < ' dog ' true This has a catch, though: the way computers usually do things, they order capital letters as coming before lowercase letters. ) This means it will think 'Zoo' comes before 'ant'. downcase false true Similarly surprising is this: puts 2 puts ' 2 ' < 10 < ' 10 ' true false OK, 2 is less than 10, so no problem. But that last one?! Well, the '1' character comes before the '2' character—remember, in a string those are just characters.
But we’ll learn how to do both. Before we can add these together, we need some way of getting the string version of var1 or of getting the integer version of var2. to_f gives the float version. to_i 25 7 Notice that, even after we got the string version of var1 by calling to_s, var1 was always pointing at 2 and never at '2'. Unless we explicitly reassign var1 (which requires an = sign), it will point at 2 for the life of the program. to_i puts ' ' puts ' 5 is my favorite number! to_i puts ' Who asked you about 5 or whatever?
If you want to get different numbers again (like what happens if you never use srand), then just call srand(0). This seeds it with a really weird number, using (among other things) the current time on your computer, down to the millisecond. 6 The Math Object Finally, let’s look at the Math object. sqrt(5))/2) Math::PI is actually not a variable; it’s a constant. It doesn’t vary. Remember how I said that variables in Ruby have to start with a lowercase letter? Constants start with an uppercase letter.
