The Trunk: Kernel-nice.921.mcz

Chris Muller uploaded a new version of Kernel to project The Trunk:
http://source.squeak.org/trunk/Kernel-nice.921.mcz

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

Name: Kernel-nice.921
Author: nice
Time: 1 May 2015, 3:09:15.528 pm
UUID: 1ce76bf5-1e32-4d12-b7b1-9f23a75d37b2
Ancestors: Kernel-topa.920

Provide an exact version for #floorLog: for those Number using exact arithmetic
(as proposed in inbox Kernel-nice.721 / 11 December 2012).

Previous version was not exact, otherwise this count would have been zero:
    (-300 to: -1) count: [:n | n ~= ((10 raisedTo: n) floorLog: 10)].

Note that this won't make #log: exact, and could lead to disagreement between the two functions.
However, old behavior compatible with log: is still possible by passing the radix argument asFloat, so this is not a real problem.
