Black-Scholes in Multiple Languages

You naturally know the Black-Scholes-Merton Nobel Prize formula, but in how many languages?

I am not sure this really qualifies as fun, but what the heck...

Among the languages you'll find on this web page are Transact SQL, LyME, ColdFusion and even Icon.

But don't worry: Haskell is also included

As these are code snippets rather than programs it's less fun than it could be.

I'm unable to figure out if the Haskell implementation is correct - in the other implementations it's obvious that we have

a1 * k**1 + a2 * k**2 + a3 * k**3 + a4 * k**4 + a5 * k**5

in my very limited understanding the Haskell solution seems to have

a1 * k + a2 * k + a3 * k + a4 * k + a5 * k

Probably just me.

Too much trouble to say Horner's rule?

Sorry about that. I wanted to look at the code to make sure this is what's going on, and later your question slipped my mind...
