Abdulaziz Ghuloum 52a36d4c3f * Added sra, fixing the bignum shift bugs. 2007-09-12 23:34:21 -04:00
Abdulaziz Ghuloum ef1a828f1f * Fixed a bug in that caused exact->inexact to return nans when 
given big ratnums.  E.g.
    (exact->inexact (/ (expt 2 3000) (- (expt 2 3000) 1)))
  now returns 1.0 instead of +nan.0
