Convert int to bitmask
WebMost of your value* constants aren't actually bit masks, only value7 and value8 are. I'd define another bit mask to extract the lower bits, so I would have three bit masks in total: mask0 = 0x07 mask1 = 0x40 mask2 = 0x80. Now your function becomes. def parse_byte (byte): return byte & mask2, byte & mask1, byte & mask0. WebSep 8, 2009 · int mask = -1; mask = mask << param; mask = ~mask; This way you can avoid lookup tables and hard coding the length of an integer. Explanation: A signed integer with a value of -1 is represented in binary as all ones. Shift left the given number of times to add that many 0's to the right side. This will result in a 'reverse mask' of sorts.
