How to convert a 128-bit integer to a decimal ascii string in C?

Question

I\'m trying to convert a 128-bit unsigned integer stored as an array of 4 unsigned ints to the decimal string representation in C:

unsigned int src[] = { 0x1         


        

Answer 1

@Alexey Frunze's method is easy but it's very slow. You should use @chill's 32-bit integer method above. Another easy method without any multiplication or division is double dabble. This may work slower than chill's algorithm but much faster than Alexey's one. After running you'll have a packed BCD of the decimal number
