BUILT-IN FUNCTIONS
To achieve this output, cell C17 was used as the value to be rounded. Recall from Figure E-21 that cell
C17 had the formula =AVERAGE(G2:G14). The following ROUND formula would produce the same output in
cell G17: =ROUND(AVERAGE(G2:G14),2). In this case, Excel evaluates the formula
First, the
AVERAGE function is evaluated, yielding the average with many digits. That value is then input to the
ROUND function and rounded to two decimal places.
The ROUNDUP function works much like the ROUND function. ROUNDUP
inside out.
s output is always rounded
up to the next value. For example, the value 4 would appear in a cell that contained the following formula:
=ROUNDUP(3.12,0). In Figure E-22, if the formula in cell G17 had been =ROUNDUP(AVERAGE(G2:G14),2),
the value 96 would have been the result. In other words, 95.54 rounded up with no decimal places
becomes 96.
COUNTIF Function
The COUNTIF function counts the number of values in a range that meet a specified condition. The syntax is:
￿
COUNTIF(range of data, condition)
The condition is a logical expression such as
=1
,
>6
,or
=F
. The condition is shown with quotation
marks, even if a number is involved.
Assume that you want to see the number of female runners in cell C18. Figure E-23 shows the formula
used.
FIGURE E-23
COUNTIF function used in cell C18
The logic of the formula is: Count the number of times that
appears in the data range E2:E14.
As another example of using COUNTIF, assume that column H shows the rounded ratio of the runner
F
s
height in inches to the runner’s time in minutes (see Figure E-24).
