r932 r933 5 5 Version 0.4 (released DATE) 6 6 7  interface of median and percentile functions are modified. They8 now take iterators rather than containers.7  interface of median, percentile, and mad functions are 8 modified. They now take iterators rather than containers. 9 9  is_double(), is_int(), and is_float() return true also when string 10 10 is a nan or int.
