C = bitget(A, bit) range limit

Why the bitget range is only 1-52 bit, not covering 64 bit numbers?
Is a simple way to get around that? If I want to check a bit of any 64 bit number?
>> bitget(hex2dec('FFFFFFFF'),52) = 0
>> bitget(hex2dec('FFFFFFFF'),53)
??? Error using ==> bitget; BIT must be integers between 1 and 52 for double.
>> bitget(hex2dec('1FFFFFFFFFFFFF'),52) =1
>> bitget(hex2dec('20000000000000'),52)
??? Error using ==> bitget; Exceeded value of bitmax.

It might depend upon the release you are using, but in current releases bitget is not restricted to 52 bits.
Your major problem at the moment is that hex2dec() outputs a double precision number.
Try
bitget( sscanf('FFFFFFFF', '%lx'), 53)
