* Use a better algorithm for rounding sqrt results. Change the FIXME aboutReid Spencer2007-03-021-8/+12
| | | | | | | | | | this to a NOTE: because pari/gp results start to get rounded incorrectly after 192 bits of precision. APInt and pari/gp never differ by more than 1, but APInt is more accurate because it does not lose precision after 192 bits as does pari/gp. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@34834 91177308-0d34-0410-b5e6-96231b3b80d8
