[QUOTE="Me, post: 2453262"] I have an large integer in this format It looks like you're trying to convert a base-256 number to a base-900 number (i.e. all the the xN's are in the range [0, 255]). If this is the case, then you can do this: unsigned long long x = x1; x = x<<8 | x2; x = x<<8 | x3; x = x<<8 | x4; x = x<<8 | x5; And then to get y1..y5: y5 = x % 900; x /= 900; y4 = x % 900; x /= 900; y3 = x % 900; x /= 900; y2 = x % 900; x /= 900; y1 = x; [/QUOTE]
