Sorry - no time from my side these days for Pharo to send a slice.

Looks like here is an updated version:

There has been great interaction with Juan, so these changes are now  
stabilizing.
The changes are :
- let sqrt be exact when possible, (4 sqrt) -> 2 instead of 2.0
- answer better estimate than Float infinity when possible
   (100 factorial squared + 1) sqrt isFinite
- do the same for nthRoot: and handle raisedTo: aFraction with nthRoot:
- correct (-3/2) ln which produce an infinite loop rather than raising a  
DomainError
I prefer a single SLICE containing all these related materials, and it will  
be gathered into this issue.
