Hey,
The sqrt function is not doing what I want. This is what I want:
round sqrt(2)
The problem is that sqrt() returns a Floating value and round wants a

Sigh... never fails. Spend an hour trying to solve a problem, and a
minute after you write to the list you find the solution. I need
brackets around sqrt. I'm surprised though. I don't

I don't understand why it dosn't work without brackets.
Function application is left associative in Haskell.

because x y z parses as (x y) z, so round sqrt 2 parses

nitpicky detail:
() - Parenthesis
{} - Braces

Sorry to be pedantic, but using the wrong terminology confuses me and
I'm sure others as well.
