interger to binary

Hi,

Thanks a lot to all of you for your help. This looks very promising. I will test it on Monday.

Regards, Marjolaine.

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

Hi,

I was wondering if python has the equivalent of the matlab bitget.m function.

I have a large 2 dimensional variable of type uint32 which I must convert to binaries and then find if bit 23 of the binary for each point is 0 or 1. 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.

Any suggestions?

Thanks, Marjolaine.
