Examples of Ambiguous Presentation of Significant Figures
Significant Figures of $186 \, 000 \, 000$
Consider the number $n$ presented as:
- $n = 186 \, 000 \, 000$
It is impossible to tell exactly how many significant figures $n$ is presented to.
This could be any number from $3$ to $9$.
Suppose $n$ is presented to $5$ significant figures.
Then $n$ can be written in scientific notation as:
- $n = 1 \cdotp 8600 \times 10^9$
and the matter is immediately clear.
If desired, $n$ can also be presented as:
- $n = 168 \cdotp 00$ million
