issue with "compliling" code with Math expressions

Hi - Thanks - I've just reproduced it here. It seems to be something to do with floating point numbers when used as function arguments.

Even something like this fails:

function F(x){
  "compiled";
  print (x-0.54);
}

function G(x){
  print (x-0.54);
}

for (var i=0;i<10;i++) {
  print("----",i);
  F(i);G(i);
}

I'll look into this now and see if it's an easy fix
