Detailed explanation-1: -100.00 has five significant figures. This is because trailing zeros do count as sig figs if the decimal point is present.
Detailed explanation-2: -“100.” has three significant digits because of the decima point at the end. To determine the number of significant digits, you count the digits starting at the first nonzero digit and ending at the last nonzero digit if there is no decimal point or the last digit after the decimal if there is one.
Detailed explanation-3: -The number “10.” is said to have two significant digits, or significant figures, the 1 and the 0. The number 1.0 also has two significant digits. So does the number 130, but 10 and 100 only have one “sig fig” as written. Zeros that only hold places are not considered to be significant.
Detailed explanation-4: -Definitions, 1m=100 cm, and exact counts have an infinite number of significant figures.
