Rounding of numbers

Indicate how results should be reported, including rounding of numbers, final units, uncertainty and level of confidence. 

Are they original data ", and "How do we know " It is sometimes difficult to reconstruct computer generated data points because of dilution factors, rounding of numbers, etc. Check to see if you can recalculate the numbers before you have to do it for an auditor. 

The result of Equation 3.31 should be viewed as the maximum number of turns, sinee any more turns would inerease the seeondary s induetanee and take longer to empty the eore s energy. This ealeulation will always result in a noninteger number of turns. Many eores do not support fraetional turns, so round this number to the elosest fraetional turn that the eore will allow. 

If the pressure coefficient is now, or was in an earlier step, 5% uiutei the 0.29 value, calculate a new mean blade velocity using the rounded off number of stages and the original pressure coefficient, 0.29. Use the calculated blade velocity in the subsequent step for compressor speed Calculate the speed. 

To find the empirical formula of vitamin C from the data in Example F.l we must express the ratios of numbers of atoms as the simplest whole numbers. First, we divide each number by the smallest value (3.41), which gives a ratio of 1.00 1.33 1.00. Molecules contain only whole numbers of atoms, and one of these numbers is still not a whole number. Hence, we must multiply each number by the correct factor so that all numbers can be rounded off to whole numbers. Because 1.33 is Vi (within experimental error), we multiply all three numbers by 3 to obtain 3.00 3.99 3.00, or approximately 3 4 3. Now we know that the empirical formula of vitamin C is C3H403. 

Comment The sequence of digits in each coefficient depends on the precision (e.g., three decimal places) and number of tabulated values (34, 50, or 64), the form of the optimization software used (Hewlett Packard HP71B Curve Fit Module), and the number of coefficients chosen (3. .. 8). Discrepancies between the approximated and the real table entries of up to j-LSD could be due either to insufficiencies of the algorithm or the rounding of table entries. The few LRR that are above 1% do not pose a risk for practical applications. 

Round, Column Width) permits the raw data presentation to be adjusted by choosing the number of significant digits to which the numbers are rounded to, see Presentation of Numbers below the column width is automatically adjusted. 

Peptoid hbraries have also yielded compounds active in the disruption of RNA-protein interactions. Compounds not derived from library syntheses are discussed in Section 1.4.1. A peptoid 9-mer with a number of cationic groups was discovered (Fig. 1.4) after several rounds of mixture deconvolution, that was able to block the interaction of HIV-1 Tat protein with TAR RNA at nanomolar concentra-... 

We have seen that we must sometimes reduce the number of digits in our calculated result to indicate the accuracy of the measurements that were made. To reduce the number, we round off numbers other than integer digits using the following rules. 

The data shown in Table 7.3 are from one round of a proficiency testing scheme for the determination of moisture in barley. There are a number of different...
