Re: [Matplotlib-users] interger to binary

You could do something like:

def bitget(value, bit_number):
    return (value & (1 << bit_number)) != 0

which will return True or False for the given bit number, and this 
function works on numpy arrays.  (Bits are numbered base-0 -- I don't 
know if that matches matlab).

Hope that helps,
Mike

The matlab bitget function is ideal for that but I can't find much in python. The only thing I found was binary_repr which converts to a sting and can only be used for 1 point at a time.
