42500 - 1907.25 40592.8 The default output display is six digits but the stored value is accurate. For example, use InputForm % // InputForm 40592.75 Rationalize[%%] 162371/4 % == %%% True Bob Hanlon ---- Li Zhengji <zhengji.li at gmail.com> wrote: ============= Hi all, 42500 - 1907.25 = 40592.8 (http://www.wolframalpha.com/input/?i=42500+-+1907.25) I do believe that it is because Mathematica "thinks" it's *better* to limit the result to six digits, so 0.75 is rounded to 0.8. But, don't you think that the result is a little strange, or inaccurate? -- Li Zhengji
