I'm using ruby for my research purpose, and as everyone knows computer science is all about log function whose base is 2. Unfortunately, Math module does not contain log2 though it has log10. What do you think about adding log2 to Math? Yes, I know that adding log2 is way so simple because I can open Math module and add log2 method, but I've had to that ALWAYS.
