**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 = 10^{3}, but not by 10^{4}.

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.
