Rounding/Examples/0.02006 to Three Significant Figures

Example of Rounding

$0 \cdotp 02006$ rounded to $3$ significant figures is $0 \cdotp 0201$.

This is because $0 \cdotp 02006$ is closer to $0 \cdotp 0201$ than it is to $0 \cdotp 0200$.

Also note that the $0$ immediately to the right of the decimal point does not count as one of the significant figures.
