I need some help

[Bahadır SEVİNÇ]

Hello
  I am writing a whole program which is analyz a elegtromagnetic wave. This
is ok but in the program I use a lot of constant for example pi,epsilon etc.
I want to ask that
  how I use a constant in Haskell ?

However the user of the program give some argument then program is starting.
And I want to use this arguments for example at the end of the program. What
will I do.

Thanks
