I rarely need to chop off fractional parts without also making the result exact.
That might be convenient, but it's philosophically dubious. Consider rounding the
inexact value 5.49 plus or minus .05. Saying the answer is "exactly" 5 is
claiming more certainty than you actually have: it might be 6.
Is `inexact->exact' the only function in the standard library allowed to
be used to say, "Aw, screw it, I know it's inexact but I want a rational
number anyway"?
Or is your objection more about the name?
