Nicolas Cellier uploaded a new version of KernelTests to project The Trunk:
http://source.squeak.org/trunk/KernelTests-nice.221.mcz

==================== Summary ====================

Name: KernelTests-nice.221
Author: nice
Time: 22 May 2012, 10:46:19.006 pm
UUID: c4f656c0-9acc-426f-b05e-f80f3623ff33
Ancestors: KernelTests-nice.220

Now that Float print exactly, avoid using low level private implementation #absPrintExactlyOn:base: in tests.
We might deprecate it in the future.
