In a decimal number, the precision is given by the number of decimal places.

For example, the number 2.7 has precision 1 and the number 5.609 has precision 3.

In the number 345.82, the precision is 2 and the digit that defines this precision is the digit 2, since it's in the last decimal place of the number.

Therefore the answer is 2.
