Subject: real numbers and integer-expt.
Date: Wed, 13 Mar 2002 02:36:38 -0600	[thread overview]
Message-ID: <876640j23t.fsf@raven.i.defaultvalue.org> (raw)


integer-expt says:

  SCM_DEFINE (scm_integer_expt, "integer-expt", 2, 0, 0,
              (SCM n, SCM k),
	      "Return @var{n} raised to the non-negative integer exponent\n"
	      "@var{k}.\n"
	      "\n"

but in the code we check to see if k satisfies SCM_REALP and if it
does, we coerce it to an int and see if we get any lossage.  If we
don't then we decide it's OK to use it.  Is that what we want, or
should callers be required to use inexact->exact when appropriate?

Thanks
