# Are trailing zeros significant?

Trailing zeros (the right most zeros) are significant when there is a decimal point in the number. For this reason it is important to give consideration to when a decimal point is used and to keep the trailing zeros to indicate the actual number of significant figures.

Herein, are trailing zeros after decimal significant?

The trailing zeros do not count as significant. Trailing zeros in a number containing a decimal point are significant. For example, 12.2300 has six significant figures: 1, 2, 2, 3, 0, and 0. The number 0.000122300 still has only six significant figures (the zeros before the 1 are not significant).

Additionally, what are the 5 Rules of significant figures? Significant Figures

• Annotation category:
• RULES FOR SIGNIFICANT FIGURES.
• All non-zero numbers ARE significant.
• Zeros between two non-zero digits ARE significant.
• Leading zeros are NOT significant.
• Trailing zeros to the right of the decimal ARE significant.
• Trailing zeros in a whole number with the decimal shown ARE significant.

Similarly one may ask, what is the trailing zero rule?

In mathematics, trailing zeros are a sequence of 0 in the decimal representation (or more generally, in any positional representation) of a number, after which no other digits follow. For example, 14000 has three trailing zeros and is therefore divisible by 1000 = 103, but not by 104.

What are leading and trailing zeros?

Zeros attached to the beginning of a number in this way are called leading zeros. In decimals, this idea of zeros that don't add value to a number can be extended to trailing zeros. A trailing zero is any zero that appears to the right of both the decimal point and every digit other than zero.
