Excel formulas

BayAPS PP has been extended to cover the requirements that were described above. Last but not least the easy to use Excel interface of BayAPS PP led to an interesting idea of a user The end-user can create a report writer based on simple Excel formulas. These Excel formulas such as VLOOKUP reference and combine information from several BayAPS PP sheets and present it to the user as a list in the traditional layout known to the personal in the production plant. 

Again, the Excel formula for component A is given in Figure 3-30. 

Not only is it an excellent formula to study, it is also an effective formula that is frequently used in clinical practice. 

Excel formulas are discussed in much greater detail in Chapter 3. 

Most fields in a database will contain values that have been entered as text, numbers or dates. A database may also contain calculated fields, containing values that are calculated by using Excel formulas. 

The area of each Gaussian curve is equal to 1.000 thus the total area under the curve shown in Figure 9-17 is 2.000. The Excel formula used to calculate y is as follows (m is the position p and s is the standard deviation a) ... 

The variance can easily be obtained using the Excel function VAR. Equation 11-16 for the pooled estimate of the standard deviation is implemented, for example, by using the Excel formula... 

Array formulas are now covered in depth in a separate chapter, rather than being discussed in the chapter on Excel formulas. 

Excel formulas always begin with an equals sign [ = ]. 

The expression you just typed is called a formula. In Excel, formulas begin with an equals sign [ = ] followed by the desired numerical expression. Notice that the difference between the contents of cell B3 and cell B4 is displayed in cell B5. Now continue entering data until your spreadsheet looks like the one in Figure 3-4. 

Our task is now to translate this equation into an Excel formula and type it into cell Bll as shown ... 

Prepare a spreadsheet similar to the one shown in Figure 3-7 for the gravimetric determination of nickel using dimethylglyoxime. See Section 37B-3 for details. Use the worksheet from Problem 3-9 to calculate the molar mass of Ni(DMG)2 if it is available. 3-4. Write an Excel formula using the FIND and MID functions to eliminate the square brackets and the uncertainty from the atomic mass of lithium in the lUPAC table and display the numeric characters of the atomic weight. 

Devise an Excel formula for elements 43, 61, 84 to 89, and 93 to 114 that will automatically remove the square brackets from the lUPAC table of atomic masses and eliminate the VALUE error described in Section 3B-2. 

Devise an Excel formula using the FIND and MID functions that will automatically display the uncertainties of the atomic masses in the lUPAC table. 3-7. Use the worksheet of Figure 3-15 to calculate the molar masses of the following compounds. 

Table 10.6 shows the Microsoft Excel formulae used in the calculation spreadsheet. 

For readers benefit we also show the Excel formula in Figure 19-6. This shows how the Z-spread is calculated for ease of illustration, we have assumed that the calculation takes place for value on a coupon date, so that we have precisely an even period to maturity. 

The Hex output is converted into decimal format by using an Excel formula. The following equation is used to translate the decimal output into a voltage reading.
