float(Amount) does not convert a number into a float -- it is a test for 
a float, and I assume in your case, it fails because you have a bounded 
real, so it fails back into the locate/2 labelling.

You should check the documentation when you are using a built-in you are 
not familiar with -- ECLiPSe allows you to do this easily from the 
top-level, you simply have to type help <predicate spec>, in your case,
help float/1. Als0, since variables in ECLiPSe cannot be destructively 
assigned, there is no way you can perform a conversion with a predicate 
with only one argument.

To convert a number into a float, you need to use float/2 (see the 
documentation).
