Unfortunately that returns a single decimal fraction (not a ratio of two integers) if the non-programmable "Change apparent integers into exact integers" setting in CAS Settings (page 1, check box at end of line 3) is unchecked. EDIT: Very non-elegant, but this works: print(string(N)+"/"+string(D)) EDIT 2: Do NOT use the following method unless both N and D are always very small integers. If either N or D are large, it is prone to error, and it depends on the value of the system variable epsilon (CAS Settings, page 2): print(exact(N/D)) <0|ɸ|0> -Joe- |
