WebApr 9, 2012 · Dropping M least significant bits is a simple shift to the right: k >> M; Now your algorithm for cutting out from M to N becomes a two-step process: you shift the original value M bits to the right, and then perform a bit-wise AND with the mask of N-M ones. WebSep 29, 2008 · The &, and ^ operators in Python work just like in C. The ~ operator works as for a signed integer in C; that is, ~x computes -x-1. You have to be somewhat careful with left shifts, since Python integers aren't fixed-width. Use bit masks to obtain the low order bits.
