It would be nice to have.  Are there any other procedures
that are not supported by numbers egg?

BTW, I felt the use of numbers egg made the execution slow,
even if it's just a fixnum calculation. Is is an expected feature?

Following is a small test in chicken 2.2,
but I'm not sure if it is correct to measure the performance.

% csi -eval '(print (cpu-time))(let loop ([i 0]) (or (> i (expt 2 17)) (loop (+ 
i 1))))(print (cpu-time))'  
1
142
% csi -eval '(use numbers)(print (cpu-time))(let loop ([i 0]) (or (> i (expt 2 
17)) (loop (+ i 1))))(print (cpu-time))'
1
1289
