The answer is the last digit is "estimated".
The Scientific notation or configuration shows a number in exponential notation, by replacing some portion of the number with E+n, where E (which remains for Exponent) duplicates the first number by 10 to the nth power. For instance, a 2-decimal Scientific notation shows 12345678901 as 1.23E+10, which is 1.23 times 10 to the tenth power. Hope this helps!
