Split integer from atom in prolog -


i want split integer atom. ideas how that?

sample query:

?- split_int('nc(4)', n).      % given:    atom 'nc(4)' n = 4.                         % expected: integer  4

in swi prolog, should able like

?- term_to_atom( nc(n) , 'nc(4)' ). n = 4.

and want. in sicstus, looks need use library(codesio). should let this:

atom_to_term( , t ) :-   atom_codes( , cs ) ,   read_from_codes( cs , t )   .

though you'll have ensure atom terminated period/full stop. 'nc(4)' won't work, 'nc(4).' work.
