Hello !

"a" is an exact number, I suppose?
So Log[a] is exact! If you want a machine-precision result, type : Log[N[a]]

Or, for example :  Log[3.0] instead of Log[3] !

I have Mathematica 5.0.1.  When I attempt to get the Log of a number "a" 
by entering Log[a], it does not return the value but echoes back: 
Log[a].  How is this fixed?
