refactor(library/data/num): break into pieces to reduce dependencies 2014-11-07 08:21:42 -08:00			`import logic data.num`
feat(frontends/lean): max precedence used by Lean is not max_uint anymore The motivation is to allow users to define notation with higher precedence than function application. 2014-11-07 07:51:40 -08:00			`open num`
