IF=IF(logical_test, [value_if_true], [value_if_false])

The AND function

Microsoft® Excel® Logical Functions

Syntax:

=AND(logical1, [logical2], ...)

Arguments:•logical1 Required

The first condition that you want to test that can evaluate to either TRUE or FALSE.

•logical2, ... Optional Additional conditions that you want to test that can evaluate to

either TRUE or FALSE, up to a maximum of 255 conditions.

The AND function


Description:• Returns FALSE if one or more arguments is FALSE

• Otherwise, all arguments must evaluate TRUE

Remarks:• Arguments must evaluate to logical values• Arguments must be arrays or references that contain logical

values• Text and empty cells are ignored in arrays or references

Errors:#VALUE – If no logical values exist in a specified range

The AND function – EXAMPLE 1


The AND function – EXAMPLE 2


The OR function


Syntax:

=OR(logical1, [logical2], ...)

Arguments:•logical1 Required

The first condition that you want to test that can evaluate to either TRUE or FALSE.

•logical2, ... Optional Additional conditions that you want to test that can evaluate to

either TRUE or FALSE, up to a maximum of 255 conditions.

The OR function


Description:• Returns TRUE if one or more arguments is TRUE

• Otherwise, all arguments must evaluate FALSE

Remarks:• Arguments must evaluate to logical values• Arguments must be arrays or references that contain logical

values• Text and empty cells are ignored in arrays or references

Errors:#VALUE – If no logical values exist in a specified range

The OR function


The NOT function


Syntax:

=NOT(logical)

Arguments:•logical Required

A value or expression that can be evaluated to TRUE or FALSE.

The NOT function


Description:• Reverses the value of its argument.

Remarks:• If logical is FALSE, NOT returns TRUE• if logical is TRUE, NOT returns FALSE

Errors:None

The NOT function


The IF function


Syntax:

=IF(logical_test, [value_if_true], [value_if_false])

Arguments:•logical_test Required

Any value or expression that can be evaluated to TRUE or FALSE.•value_if_true Optional

• The value that you want to be returned if the logical_test argument evaluates to TRUE.

• If logical_test evaluates to TRUE and the value_if_true argument is omitted (that is, there is only a comma following the logical_test argument), the IF function returns 0 (zero).

• To display the word TRUE, use the logical value TRUE for the value_if_true argument.

The IF function


Syntax:

=IF(logical_test, [value_if_true], [value_if_false])

Arguments:•value_if_false Optional

The value that you want to be returned if the logical_test argument evaluates to FALSE.

If logical_test evaluates to FALSE and the value_if_false argument is omitted, (that is, there is no comma following the value_if_true argument), the IF function returns the logical value FALSE.

If logical_test evaluates to FALSE and the value of the value_if_false argument is omitted (that is, in the IF function, there is a comma following the value_if_true argument), the IF function returns the value 0 (zero).

The IF function


Description:• The IF function returns one value if a condition you specify

evaluates to TRUE, and another value if that condition evaluates to FALSE.

Remarks:• Up to 7 IF functions can be nested as value_if_true and

value_if_false arguments to construct more elaborate tests. (2003)

• Up to 64 IF functions can be nested as value_if_true and value_if_false arguments to construct more elaborate tests. (2007)

Question (MIS, Ch 5) To accelerate their work, application developers can use one of several _____ programming languages, such as Microsoft Visual Basic, Borland Delphi, Micro Focus COBOL, ASNA Visual RPG, and Visual C++.

Answer visual

MIS PRACTICE

Question (MIS, Ch 4) What factors make one computer more powerful than another?

Answer The two major factors to consider are processing speed and memory capacity. A computer’s speed is determined, among other factors, by the CPU clock rate (measured in MHz or GHz), and the amount of information the CPU can process per cycle (determined by the size of the data word and the capacity of internal data communication, which is often referred to as bus width). However, the architecture of the various computer components also plays a significant role in determining processing speed. To mention one, consider the discussion of multi-core CPUs. When two computers are built with the same components except the number of cores, the computer with the greater number of cores is faster.

Which of the formulas below calculates the correct total price to charge the trucker for the diesel they have pumped based on the following conditions:A- no discount (zero dollars off the total amount due) if a trucker purchases less than 50 gallons of dieselB-a 5% discount on all diesel purchased if the person dispenses at least 50 gallons into their tank

Sample Questions

Assume that cell A1 shows the total quantity (in gallons) of fuel purchased and cell B1 is the price per gallon. Provide a formula that will correctly calculate the total amount that a person should pay, after the discount (if any) has been applied. =IF(A1<50, A1*B1, A1*B1*95%) and then apply some algebra to get:

=A1*B1*IF(A1<50, 1, .95) note the different format (no percent)
