What you need to know in order to Identify significant figures with concise rules
- All non-zero digits are significant.
- Zeros between non-zero digits are significant.
- Leading zeros are never significant.
- In a number with a decimal point, trailing zeros, those to the right of the last non-zero digit, are significant.
- In a number without a decimal point, trailing zeros may or may not be significant.
Sometimes more information is required for clarifing the significance of trailing zeros - additional graphical symbols or details about the errors.
