Rounding to significant figures

The method of rounding to a significant figure is often used as it can be applied to any kind of number, regardless of how big or small it is.

To round to a significant figure:

• Check the first non-zero digit if you want to round to one significant figure while doing so.
• If rounding to two significant figures, have a look at the digit following the first non-zero digit.
• After the required place value digit, draw a vertical line to reveal the following digit.
• If it's five or more, add one to the previous digit.
• Keep the previous digit the same if it's 4 or less.
• If there is a decimal point, stop there and place zeros in any spaces to the right of the line.

Round off to four significant figures:

$(i)36.789\approx36.88\\(ii)1.0084\approx1.008$
