Significant Figures - CalCon 对比 Professional Dental Placements 的使用情况和统计数据

Significant (symbolic) numbers are the digits used to represent the modified number. Only the landmark farthest to the right is uncertain. The farthest right digit has a certain error in value, but it is still significant. Exact numbers have an exactly known value. There is no error or uncertainty in the value of the correct number.
