I think you want to set the global variable %enumer:true here.
%enumer : true;
a:[ [sin(0),exp(0)] , [sin(1),exp(1)]] ;
ev (a, numer);
=> [[0, 1], [.8414709848078965, 2.718281828459045]]
float also works here, but you would have to apply it every
time you want %e to evaluate to a number.
Maxima treats exponentials differently from other functions such
as trigonometric functions; this is a bug, in my opinion.
Hope this helps
