What  are you  writing about?  Figments  of your  imagination or  real
concrete systems?


[20]> (typep (fact 100)  'fixnum)
NIL
[21]> (typep (fact 100)  'bignum)
T
[22]> (typep (/ (fact 100) (fact 99)) 'fixnum)
T
[23]> (typep (/ (fact 100) (fact 99)) 'bignum)
NIL
[24]> (/ 1 3)
1/3
[25]> (/ 1.0 3)
0.33333334

Where do you see "infinite precision by default"?
