The first things to look for here are non-zero digits, which as you know are always significant.

This measurement has a total of #5# non-zero digits


so right from the start you know that it will have at least five significant figures.

Now focus on the trailing zero. Trailing zeros are zeros that follow a non-zero digit and are not followed by other non-zero digits.

When trailing zeros follow a non-zero digit and a decimal place, they are considered significant. This means that your measurement will contain #6# significant figures

#238.230 -># five non-zero digits and one significant trailing zero
