A function formula has three components:
–
–
–


the equal sign
a function name
an argument
The argument is a value, cell reference, range, or
text that acts as an operand in a function formula.
Example:
=SUM (E4:E22)

Using Logical Function Formulas
Excel – Lesson 5

9

Logical functions, such as the IF function, may be
used to display text or values if certain conditions
exist.
For example the IF function will determine whether a
student has passed or failed a course. The function
formula IF(C4>60,“PASS”,“FAIL”) will display “PASS”
if the value in C4 is greater than 60 and “FAIL” if the
value in C4 is not greater than 60.

Function formulas are special formulas that
do not require operators.
Excel has more than 300 function formulas.
Function formulas may be used to perform
mathematical, statistical, financial, and
logical operations.
Function formulas may also be used to
format text and insert dates and times.
