WebSignificant figures (also known as the significant digits, precision or resolution) of a number in positional notation are digits in the number that are reliable and necessary to indicate the quantity of something. If a number expressing the result of a measurement (e.g., length, pressure, volume, or mass) has more digits than the number of ... WebJun 15, 2024 · An exception to this rule occurs when multiplying a number by an integer, as in 12.793 × 12. In this case, the number of significant figures in the answer is determined by the number 12.973, because we are in essence adding 12.973 to itself 12 times. The correct answer is therefore 155.516, an increase of one significant figure, not 155.52.
WebRemember these two rules for stating a number with an uncertainty: (1) The uncertainty should be stated with 1 or 2 significant figures. (2) A value and its uncertainty should be stated to the same precision: they should have the same number of digits past the decimal point. Usually, if the leading nonzero digit in the uncertainty is greater ... http://www.physics.smu.edu/cooley/phy3305/sigfigs.pdf
