Why this ticket? We already have

sage: log_b?
Type:		function
Base Class:	<type 'function'>
String Form:	<function log at 0x29b33f0>
Namespace:	Interactive
File:		/Users/michaelabshoff/Desktop/sage-3.1.3.rc0/local/lib/python2.5/site-packages/sage/misc/
Definition:	log_b(x, b=None)
        Return the log of x to the base b.  The default base is e.
            x -- number
            b -- base (default: None, which means natural log)
        NOTE: In Magma, the order of arguments is reversed from in
        SAGE, i.e., the base is given first.  We use the opposite
        ordering, so the base can be viewed as an optional second

One could obviously implement log10, but why pollute the global namespace even more?

  • Resolution set to invalid
  • Status changed from new to closed

Pari, Maple, and Mathematica all don't do this. We should not do this in Sage either. It is trivial to implement in terms of existing functions.
