Rules for identifying significant figures
1.Zeros between two non-zero digits ARE significant
2.Leading zeros are NOT significant.
3. Trailing zeros in a whole number with the decimal shown ARE significant.
4. Trailing zeros in a whole number with no decimal shown are NOT significant.
5. Trailing zeros to the right of the decimal ARE significant.
