In positional notation, significant figures are digits in a number that is trustworthy and absolutely essential to represent the quantity of something. The rules for which digits in a positional notation are significant are simple. If we were to multiply 40, 6 by 19, 14, you would get a product of 777, 084. 0205.60: here the leading zero is dropped via rule #1, the zero between 2 and 5 is preserved as it is between two significant digits and the trailing zero is preserved as it is to the right of the decimal point (both following rule #2), 470.0: here the trailing zero is significant as it is to the right of the decimal point, while the other zero is also significant since it sits between two significant figures: the seven to the left and the zero beyond the decimal point, 1001.05: the first two zeroes are between significant digits greater than zero, the third zero is also significant since it is both to the right of the decimal point and is between two significant digits, If the digit immediately to the right of the. (27.2 x 15.63) 1.846 = 230.3011918 (this is what you calculator spits out) In this case, since your final answer it limited to three sig figs, the answer is 230. Suppose you have a numeric figure 0.007667 and want four decimal numbers. Example inputs are, 3500, 35.0056, 3.5 x 10^3 and 3.5e3. This is a variable, because it will change depending on the number being rounded. All figures are significant except the following: Note that the above rules mean that all non-zero digits (1-9) are significant, regardless of their position. Any digit that is not 0 is always significant. Zeros after numbers to the right of the decimal are significant. Enter whole numbers, real numbers, scientific notation or e notation. For example 0.00017 has 2 significant figures; therefore the correct scientific notation for this number would be \(1.7 10^{-4}\).
