In log10.mac there is the
statement:
* log10 (x) => log (x) / log (10) (if you ask for it explicitly)
How do you "ask for it explicitly"?
My attempts are %i7,8, and 9:
(%i1) load(log10);
(%o1) C:/PROGRA~1/MAXIMA~1.1/share/maxima/5.16.1/share/contrib/log10.mac
(%i2) log10(1);
(%o2) 0
(%i3) log10(10);
(%o3) 1
(%i4) log10(12/13);
(%o4) log10(12) - log10(13)
(%i5) %,numer;
(%o5) log10(12) - log10(13)
(%i6) log10(12/13),numer;
(%o6) - 0.034762106259212
(%i7) log10(x);
(%o7) log10(x)
(%i8) log10(12);
(%o8) log10(12)
(%i9) log10(12),numer;
(%o9) log10(12)
also, why does %i6 work but %i5 doesn't?
and why does %i6 work but %i9 doesn't?
