In this case, where there are no non-zero digits to the left of the decimal point, the number of significant figures is equal to the number of digits to the right of the decimal point from the rightmost figure to leftmost non-zero digit. In this case, there are four significant digits
There are three significant figures in 354. All non-zero digits are significant.
