DO NOT CROSS POST.

Bob.
It may not be the answer you were looking for but its the one I am giving based on either experience, educated guess, google or the fact that you gave nothing to go with in the first place so I used my wonky crystal ball.

Since the BigNumber representation is based on a character array, there may be faster ways to do what you want.

Doing so will require you to study and understand the library code.

Thank you all of you guys gave me the replies..
yes i want to get the how many digit in the value. but i'm trouble with the big number. in my result there are about 40 numbers. i cant convert into int value, can you tell me what's the data type of bignumber result.

From my look at the library, I think that the result is a null terminated character array.

how i get the 3rd number(6) value.??
result[2] will be 6. Note that the array index starts from 0.

as well as the how many digits have this result.
Iterate over the array looking for a match.

Code: [Select]
`int countMatch(char* num, byte position){  int i = 0;  int count = 0;  while (num[i] != '\0')  {     if (num[i] == num[position-1])      count++;    i++;  }  return count;}void setup() {  Serial.begin(115200);  char * num = "9969216677189303386214405760200";  Serial.println(num);  Serial.print("The third number from left is ");  Serial.println(num[2]);  Serial.print("The number of matches to third number is ");  Serial.println(countMatch(num,3));}void loop() {}`

That would be the third digit from the left. See reply #1 for the completely general method.
