Excel: Round 0.5 towards Even Per ASTM-E29

For example, in rounding 6 to the nearest 50, 6 is doubled giving 12 which becomes 12 when rounded to the nearest 6. ASTM does not give any warranty express or implied or make any representation that the contents of this abstract are accurate, complete or up to date. It is informational only and not an official part of the standard; the full astk of the standard itself must be referred to for its use and application.

Thus, kPa without the decimal point indicates that the modulus is reported either to the nearest 10 or 1 kPa, which is ambiguous with respect to the number of signi?

An alternative statement of the suggested rule is: In such cases, the following procedure can be used for rounding to any interval: This will be referred to as the absolute method, which is discussed in Section 5. Historical Version s – view previous versions of standard Work Item s – proposed revisions of this standard Translated Version s: The guidelines for retaining significant figures in asym and reporting of test results are presented in details.

The following applies to speci? In order to round to the nearest 50, 5, 0.

ASTM E29 – 13

If 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. As far as is practicable with the calculating device or form used, carry out calculations with the observed values exactly and round only the? The suggested e2 would report x? If you feel asttm your comments have not received a fair hearing you should make your views known to the ASTM Committee on Standards, at the address shown below.


When the number of observations is large more than 15 8. A test result is calculated as 1. ASTM International takes no position respecting the validity of any patent rights asserted in connection with any item mentioned in this standard.

Thus, any deviation, however small, outside the speci? When 12 is divided by 2, the resulting number, 6is the rounded value of 6 The average and standard deviation, unrounded, are x? Your comments are invited either for revision of this standard or for additional standards and should be addressed to ASTM International Headquarters.

Last previous edition approved in as E29 — Zeros trailing the last nonzero digit for numbers represented with a decimal point are signi? For example, a modulus strength, stated as Pa, may have as few as two or as many as six signi?

It should not be inferred that a measurement value is precise to the number of signi? Table 1 gives examples of applying this rounding procedure. Analyses on ast specimens give values of 3.

That is, the rounding unit for the speci?
