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

Microsoft® Excel® Logical Functions

Syntax:

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

Arguments:

•logical1 RequiredThe first condition that you want to test that can evaluate to either TRUE or FALSE.

•logical2, ... OptionalAdditional conditions that you want to test that can evaluate to either TRUE or FALSE, up to a maximum of 255 conditions.


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




Syntax:

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

Arguments:

•logical1 RequiredThe first condition that you want to test that can evaluate to either TRUE or FALSE.

•logical2, ... OptionalAdditional conditions that you want to test that can evaluate to either TRUE or FALSE, up to a maximum of 255 conditions.


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



Syntax:

=NOT(logical)

Arguments:

•logical RequiredA value or expression that can be evaluated to TRUE or FALSE.


Description:

•Reverses the value of its argument.

Remarks:

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

Errors:

None



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.


Syntax:

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

Arguments:

•value_if_false OptionalThe 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).


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)•If any of the arguments to IF are arrays, every element of the array is evaluated when the IF statement is carried out.

Errors:

None

Example- Nested IF

• Excel) A customer applies for a 30-year mortgage at their employer-sponsored credit union, which offers borrowing terms based on the customer's "FICO" (which has been set-up as a defined name in a worksheet) credit score. Write a formula to determine the rate. – Mortgage application denied if score is less than 600 – Interest rate of 6% if score is 600-699 – Interest rate of 5% if score is 700-799 – Interest rate of 4% if score is over 800

• 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.
