Hello Piotr,

> what if the contract is worth not "one" but 1.32 USD (etc.)?

I don't recall Simon Peyton-Jones discussing that in his paper.

Nonetheless, I will speculate. 

Recall that the following is a financial contract that pays one USD at the time of acquisition
 
     <one>USD</one>

A contract that pays 100 USD at the time of acquisition is created by scaling the "one contract"

    <scale><konst>100</konst><one>USD</one></scale>

Presumably a contract that pays 1.32 USD may be created by scaling the "one contract" by 1.32

    <scale><konst>1.32</konst><one>USD</one></scale>

Recall that "konst" is any double value.
