How do I do unsigned comparsion between two n-bit vectors having 1s and 0s?

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.

x =  '1000000100000000000000000000000000000000000001010110001111000000'

x = '1000000100000000000000000000000000000000000001010110001111000000'

y =  '0000000000000101011000111100000000000000000001010110001111000000'

y = '0000000000000101011000111100000000000000000001010110001111000000'

xs = sym(['0b' x])

xs = 

9295429630893056960

ys = sym(['0b' y])

ys = 

1517051168777152

isAlways( xs > ys )

ans = logical
