concept of significant figures

Asked by  | 15th Jun, 2008, 05:33: PM

Expert Answer:

The significant figures  of a number are those digits that carry meaning contributing to its accuracy. Generally this includes all digits except:

  • leading and trailing zeros where they serve merely as placeholders to indicate the scale of the number
  • spurious digits introduced, for example, by calculations carried out to greater accuracy than that of the original data, or measurements reported to a greater precision than the equipment supports.
