![]() Examples are numbers obtained by measuring an object with a measuring device. The amount of uncertainty depends on the accuracy of the measuring device. Measurement numbers have a value that is NOT exactly known due to the measurement procedure. For long calculation with mixed operations, enter as many digits as possible in the entire calculation set, and then round the final result accordingly.Įxamples are numbers obtained by counting individual objects and defined numbers (e.g. When using the calculator, if you do all the log calculations without storing the intermediate results, you will not determine if an error was made.Įven if you realize that an error has occurred, you will not determine where the error occurred. Enter numbers, exponential or electronic, and select an operator. Certain numbers also have an infinite number of significant digits.Īddition, subtraction, multiplication, and division of significant digits. Trailing zeros have no meaning in numbers without decimal places. Exact numbers contain an infinite number of significant digits but are usually not reported. For this reason, it is important to consider when a decimal point is used and stores trailing zeros to indicate the actual number of significant digits. Zeros to the left of the first non-zero digit are irrelevant. Trailing zeros (right-most zeros) are significant if they have a decimal point. Zeros between non-zero digits are significant. The conventions are as follows: All non-zero digits are significant. Some conventions must be followed when expressing numbers so that their significant digits are correctly indicated. You can think of exact numbers as an infinite number of significant figures. There is no error or uncertainty in the value of the correct number. Exact numbers have an exactly known value. The farthest right digit has a certain error in value, but it is still significant. Only the landmark farthest to the right is uncertain. Significant (symbolic) figures are the digits used to represent the modified number.
