What is the correct amount of significant figures?
A significant figure is any non-zero digit or any embedded or trailing zero. Leading zeros are not significant. The number may be rounded or padded with zeros to give it the correct number of significant figures. When multiplying values together, your result is only as significant as your least significant value.
How many significant figures are there in an exact number?
Certain types of numbers are considered “exact.” For example, there are exactly 16 ounces in one pound. The number 16 would have as many significant figures as needed.
How do you round to the correct number of significant figures?
Round a number to a quantity of significant figures that you provide. In rounding significant figures, when an integer contains more digits than are significant, the last significant digit has an overline to indicate that it is the last significant digit. Enter whole numbers, real numbers, scientific notation or e notation.
