Calculators and significant figures

  1. Jan 22, 2013 #1
    Dear Forum,

    why do calculators always give an incorrect number of significant figures?
    What assumptions do they make?

    thanks

    I don't believe that the concept of significant figures enters into things at all. A calculator will either give you an exact result (e.g., 2 * 5 = 10, .02 * .04 = .008) or will produce a result with as many decimal places as it is able to display.
