Shouldn't 4 also have potential to produce BigInt?
Nope -- we don't have bigints. :)

Okay, so:
1) We round to zero when going from float to int
2) Overflows, underflows, and division by zero throws an exception
3) All-float operations produce floats
4) Addition and subtraction of ints produces an int
5) Multiplication of two ints produces a bignum or an int, depending
on the result
6) Division of two ints produces a bignum
7) Strings are treated as floats for math operations
8) Any operation with a float and an int, string, or bool produces a float
9) Any operation with a bignum produces a bignum
10) The destination PMC is responsible for final conversion of the
inbound value
That seem reasonable?
