percentage in Ruby

[Li Chen]

Hi all,

How to write percentage in Ruby, for instance 1.2%? Do I have to change
it to 0.012 before I apply other operation on it? It looks like "%" is
used for other purpose in Ruby.

Thanks,

Li

Try printf("%2.2f\%", 1.2) ==> displays 1.20%

Yes, % is the modulo operator, so 1.2 percent would indeed be best
represented as 0.012 in your code.
