[racket] Question about round

Another such annoyance is than (min 1 +inf.0) => 1.0 - because if any
argument is inexact, the result is inexact. I don't think this makes sense
in the case of infinities. Infinities are very useful as initial values for
things that are being minimized or maximized, but there is always the need
for inexact->exact to protect against the (unexpected) coercion.

This is all from the original R5RS and continued in R6RS - but, we aren't
that language.

Could we get an exception to the coercions in the case of +/-inf.0? Or an
alternative min/max that don't do it?
