Haskell Question

-----------------------------------

In which module do functions like sqrt, log etc. reside?

It appears that they are in a class called Fractional, but I'm not sure which module to import to get a them...

They are part of the Prelude module.

Type classes are not what you're used to calling "classes" in object-oriented languages.  ;)

note to self:

sqrt != squrt

kill me now.

May I ask why such a drastic course of action is necessary?

-----------------------------------

because for some reason, while I was asking why sqrt wasn't in Prelude, the problem was I was unconsciously typing squrt into my code. >.<

Yep.  That'll cause problems.  ;)
