# significant digits

## significant digits

pl.n.
The digits of the decimal form of a number beginning with the leftmost nonzero digit and extending to the right to include all digits warranted by the accuracy of measuring devices used to obtain the numbers. Also called significant figures.

## signif′icant dig′its

n.pl.
all the nonzero digits of a number and the zeros that are included between them or that are final zeros and signify accuracy: The significant digits of 0.01230 are 1, 2, 3, and the final 0. Also called signif′icant fig′ures.

## sig·nif·i·cant digits

(sĭg-nĭf′ĭ-kənt)
The digits in a decimal number that are warranted by the accuracy of the means of measurement. Significant digits are all the numbers beginning with the leftmost nonzero digit, or beginning with the first digit after the decimal point if there are no nonzero digits to the left of the decimal point, and extending to the right. For example, 302, 3.20, and 0.023 all have three significant digits.

We report numbers with too many significant digits (often by converting from English to metric units) and without error margins, mostly because we either have only one rep or we don't want to draw attention to imperfections in the data.
Leading digits (LD) or first significant digits are the first digits of numbers appearing on the left.
