x = '1000000100000000000000000000000000000000000001010110001111000000'
y = '0000000000000101011000111100000000000000000001010110001111000000'
Let's say x is the binary representation of a n-bit unsigned number. y is also same.
I want to have unsigned comparison between both of them. That means x(1) and y(1) are the MSB and the comparsion should start from there till we reach LSB. I think if I use bin2dec then there will be a flintmax issue for n>53.
Thanks.

Ran in:

x = '1000000100000000000000000000000000000000000001010110001111000000'
y = '0000000000000101011000111100000000000000000001010110001111000000'

xs = sym(['0b' x])
xs = 
9295429630893056960
ys = sym(['0b' y])
ys = 
1517051168777152
isAlways( xs > ys )
ans = logical
