In mathematics, significant figures or significant digits are the digits of a number that are meaningful in terms of accuracy or precision. Precision refers to the closeness between two or more quantities to each other under the same condition. On the other hand, accuracy represents the closeness between the measurement and the accurate number.
In a given number, all non-zero numbers are considered significant. For instance, there are 4 significant digits in the number 9431.
Any zeroes that come in between two non-zero digits are significant. For instance, in the number 109.3001, there are 7 significant numbers.
A number that starts off a number is not a significant figure. In such a number, the zeroes are nothing more than placeholders. For instance, in the number 0.0321, although in total there are 5 numbers, there are only 3 significant figures- 3, 2, and 1.
Zeroes that are placed on the right of the decimal point and are not followed by a non-zero digit are considered significant. For instance, the number 1010.00 has 6 significant digits.
In measurement, any zeroes that are on the right of the non-zero digit are considered significant. For instance, in the measurement 1280m, there are four significant digits.
For a number in scientific notation: N × 10x, all digits comprising N are significant by the first 6 rules; “10” and “X” are not significant. For instance, in 460.03 × 10 9 there are 5 significant figures- 4, 6, 0, 0, and 3. Neither 10 nor 9 are significant
In a given number, all non-zero numbers are considered significant. For instance, there are 4 significant digits in the number 9431.
