See also #2112563.  The test suite *used* to expect "1" / "0",
and when #2112563 was fixed the test suite had to be updated to
expect "1.0" / "0.0" instead.

This is arguably a bug in the test suite.

My 2c: I don't think it matters *which* error you get if
you divide by zero.  [$sb set Inf Inf] is going to do the wrong
thing anyway.
