  • 4.29478416 = 4.295 ( 4 significant figures)
  • 4.29478416 = 4.3 (2 significant figures)

To round a number to a certain number of significant figures,

  • Only leading 0 which comes before the decimal Point are regarded as insignificant.
  • Once the number of significant figures have been identified, the next number after this is either rounded up to 1 and added to the last value(if number is ≥5) or rounded to 0 (if number is less than 5)
