Dear friends,
What is the Haskell equivlent of log_b(a)? To clarify, log of 36 to the base 1.5.
I know it's probably bad style (because there is a specific function for this) and also likely less efficient, I prefer to use this: log a / log b Unless performance is significant, I find that more elegant than logBase.
