From 7155e47537e3707d42a675d2603386963c6d9156 Mon Sep 17 00:00:00 2001 From: Stefan Tauner Date: Fri, 13 Apr 2012 01:45:02 +0200 Subject: Support shifts with keyboard This patch also changes the shift operation itself to use MPNumber for the multiplier too. Previously a signed int was used, which led to "interesting" results for bigger numbers. This was hidden because the GUI did not allow shifts with more than 15 places.
