hi all

 

i need a little lisp-help...

 

i want to split things like this perhaps 'an3 into '(a n 3)

is there a way?

 

thanx

andré

(explode 'an3)

 

=> (a n 3)

thanx, but i see my idea don't work with that...

concrete: i want to split 2/20 into exactly '(2 20) 

 

function with numerator/denominator it will be '(1 10) - not what i need

 

also with (explode '2/20) => (1 / 1 0)

 

is there any solution?

2/20 = 1/10 

i know, but only mathematically!! -> you remember the problem with gen-stacc? => we discussed that with rangarajan?

for some functions it's necessary that 2/20 will not be "reduced" to 1/20

Yes, I have also experienced this difficulty, for example, can't distinguish between 4/4 and 2/2 because both reduce to 1! As JP points out, this is a Lisp issue, nothing to do with OM. If we are adventurous, we could implement our own "data type", for example keeping numerator and denominator separately as a cons pair (numerator . denominator) or something similar. We can write a set of functions that operate on this, and then apply reduction when actually needed. More work, of course, but Lisp gives you control.
