Hello all, I try to find some functions in Haskell library to deal with numeric such that the result in the following format (but I did not find) For example, >1/3 0.33 >1/6 0.17 >8/3 2.67 >9/3 3.00 It seems a so "baby" question, but I really did not find the answer after trying on that for some hours. Thanks for any help.
