Nicolas Cellier uploaded a new version of Kernel to project The Trunk:

==================== Summary ====================
Name: Kernel-nice.642
Author: nice

UUID: 26bbac76-79b8-4600-ac86-f60a02ad6da3
Ancestors: Kernel-nice.641
Correct my own bugs, (-3/2) log should raise a DomainError, not an infinite loop...

"This function is defined because super ln might overflow.
Note that < 1 is tested before converting to float in order to avoid precision loss due to gradual underflow."
