In a measurement the digits that are an approximation are only those in proper scientific notation. The more digits that are added to the number the more the number becomes exact.

It looks like the decimal value of Pi - however, some of the digits are wrong... 3.14159265358979
10/13 as a decimal is a recurring decimal of 6 digits: 0.769230769230... An approximation would be 0.769

It is the decimal approximation to the value of the irrational number.

The ratio of a circle's circumference to its diameter Equal to 3.14159265358979323846... (the digits go on forever without repeating) A rough approximation is 22/7 (=3.1428571...), but that is not very accurate

A decimal expansion means to write out the base 10 digits of a number. Because irrational numbers do not have a closed form, the decimal expansion will always be an approximation. Consider the irrational number pi, which has the following decimal expansion: 3.14159265... Of course there are more digits to pi than that, which is denoted by the "...". It is sadly impossible to list ALL of the digits of an irrational numbers, since if there were a finite number of digits, you could express it as a fraction, which would not be irrational.
