The first five are like @racket[->fl], @racket[fl->exact-integer],
@racket[real->fl], @racket[inexact->exact], and @racket[fl->fx], but for @tech{extflonums}.
The first six are like @racket[->fl], @racket[fl->exact-integer],
@racket[real->double-flonum], @racket[inexact->exact], @racket[fl->fx],
and @racket[fx->fl], but for @tech{extflonums}.
The @racket[extfl->inexact] function converts a @tech{extflonum} to
its closest @tech{flonum} approximation.
