Hi, I'm trying to cast a float array into a string array (for instance transforming [[2., 3.], [4., 5.]] into [['2.', '3.'], ['4.', '5.']]), I tried with astype(str) and every variation (str_, string, string_, string0), but not luck. Is there a function or a method of the array class that can fulfill my needs ? And if there is a way to add a formatting option ('1.1f' for instance), it would be even better.
