  * FIX #2271
  Faster rounding functions for Double and float with Int or Integer results.
  Fixes #2271.
  Since some glibc's have buggy rintf or rint functions and the behaviour of
  these functions depends on the setting of the rounding mode, we provide our
  own implementations which always round ties to even.
  
  Also added rewrite rules and removed trailing whitespace.
