From c3e4f7e83fd2e24a38f944765c4c37f20dad98a9 Mon Sep 17 00:00:00 2001 From: Kevin Ryde Date: Sat, 27 May 2006 22:41:09 +0000 Subject: [PATCH] (number->string): Disable 11.333 and 1.324e44 tests, as these can't be expected to come out precisely in the current implementation, and in fact don't under gcc 4.
