sorry for Vague question
i try to xl_concat 8 , 64 bit numbers to reach 512 bit number but the number before and after concatenations are not same .
for example last 64 bits of this 512 bit numbers must be 101011100101010.......11 but after concatenation these 64 bits are all zero
I want to avoid this approxiamtion .
