Two commonly accepted methods of rounding data, identified as the absolute method and the rounding method are described.

For purposes of determining conformance with these speci? The guidelines for retaining significant figures in calculation and reporting of test results are presented in details. An alternative statement of the suggested rule is: In the absence of such speci?

D29 two choices are possible, as when the digits dropped are exactly a 5 or a 5 followed only by zeros, choose that ending in an even digit. Work Item s – proposed revisions of this standard.

Under these conditions, the speci? This will be referred to as the rounding method,which is discussed in Section 6. The number of signi?


When 12 is divided by 2, the resulting number, 6is the rounded value of 6 It is informational only and not an official part of the standard; the full text of the standard itself must be referred to for its use and application.

In the applications of this practice to a speci? For example, if a buret is graduated in units of 0.

Its aim is to outline methods which should aid in clarifying the intended meaning of specification limits with which observed values or calculated test results are compared in determining conformance with specifications. The rounded value should then be compared with the speci? For example, the numbers NOTE 2—Using a calculation subroutine that has been programmed to perform the rounding procedure described in 6.

ICS Number Code This practice is intended to assist the ast, technical committees in the use of uniform methods of indicating the number of digits which are to be considered significant in specification limits, asttm example, specified maximum values and specified minimum values.
