SINDARIN: 10^10 = 1410065408

While this is technically correct for 32bit integers, it is also extremely non-intuitive for our users, who might expect

real xsect = 3.14159 * 10¹³

to work ...

I don't think that we should insist on FORTRAN semantics here ...

I implemented warnings for this kind of issue in r2369 and also used the opportunity to catch division by zero in all-integer "^{" and "/" expressions.}
