Syntax:

=YEARFRAC(start_date,end_date,[basis])

Arguments:•start_date Required

A date that represents the start date.

•end_date RequiredA date that represents the end date.

•basis OptionalThe type of day count basis to use.


Description:•Calculates the fraction of the year represented by the number of whole days between two dates (the start_date and the end_date).

Remarks:•Use the YEARFRAC worksheet function to identify the proportion of a whole year's benefits or obligations to assign to a specific term.

•Dates should be entered by using the DATE function, or as results of other formulas or functions.

•All arguments are truncated to integers.

Errors:#VALUE – If start_date or end_date are not valid dates#NUM! – If basis < 0#NUM! – If basis > 4

Description:

• Computes the difference between two dates in a variety of different intervals.

Remarks:

• If you have the interval in another cell referenced by the formula, that cell should not have quotes around the interval string.

• When calculating date intervals, DATEDIF uses the year of startdate, not enddate when calculating the yd, ym and md intervals

#REF!


Syntax:= HLOOKUP(lookup_value,table_array,row_index_num,range_lookup)


The value to search in the first row of the table or range.•table_array Required

The range of cells that contains the data. •row_index_num Required

The row number in table_array from which the matching value will be returned

range_lookup OptionalA logical value that specifies whether you want HLOOKUP to find an exact match or an approximate match.


Description:• Searches for a value in the top row of a table or an array of values, and then returns a value in the same column from a row you specify in the table or array.

Remarks:• If HLOOKUP can't find lookup_value, and range_lookup is TRUE, it uses the largest value that is less than lookup_value.

• If lookup_value is smaller than the smallest value in the first row of table_array, HLOOKUP returns the #N/A error value.


Errors:#VALUE! – If row_index_num is less than 1

#REF! – If row_index_num is greater than the number of rows in the table_array

#N/A – If range_lookup is FALSE and an exact match cannot be found

#N/A – If lookup_value is less than the smallest value in the first row of table_array

=HLOOKUP("Bearings",A1:C4,3,FALSE)Looks up Bearings in row 1, and returns the value from row 3 that's in the same column. (7)

=HLOOKUP("B",A1:C4,3,TRUE)Looks up B in row 1, and returns the value from row 3 that's in the same column. Because B is not an exact match, the next largest value that is less than B is used: Axles. (5)

=HLOOKUP("Bolts",A1:C4,4)Looks up Bolts in row 1, and returns the value from row 4 that's in the same column. (11)


Syntax:

=INDEX(array,row_num,[column_num])

Arguments:•array Required

A range of cells or an array constant.

•row_num OptionalSelects the row in array from which to return a value.

oIf row_num is omitted, column_num is required.

•column_num OptionalSelects the column in array from which to return a value.

oIf column_num is omitted, row_num is required.


Description:•Returns the value of an element in a table or an array, selected by the row and column number indexes.

Remarks:• If both the row_num and column_num arguments are used, INDEX returns the value in the cell at the intersection of row_num and column_num.

Errors:#REF! – If row_num and column_num do not point to a cell within array


Syntax:

=MATCH(lookup_value, lookup_array, [match_type])


The value that you want to match in lookup_array.

•lookup_array RequiredThe range of cells being searched.

•match_type OptionalSpecifies how Excel matches lookup_value with values in lookup_array.

oThe number -1, 0, or 1


Description:•Searches for a specified item in a range of cells, and then returns the relative position of that item in the range

Remarks:•The lookup_value argument can be a value (number, text, or logical value) or a cell reference to a number, text, or logical value.

•MATCH returns the position of the matched value within lookup_array, not the value itself.

•MATCH does not distinguish between uppercase and lowercase letters when matching text values.

Errors:#N/A – If MATCH is unsuccessful in finding a match


Value

Behavior Restrictions

1

MATCH finds the largest value that is less than or equal to lookup_value.

The values in the lookup_array argument must be placed in ascending order.

0MATCH finds the first value that is exactly equal to lookup_value.

None

-1

MATCH finds the smallest value that is greater than or equal to lookup_value.

The values in the lookup_array argument must be placed in descending order.

Default



Syntax:

=IFERROR(value,value_if_error)

Arguments:•value Required

is the argument that is checked for an error.

•value_if_error Requiredis the value to return if the formula evaluates to an error. The following error types are evaluated: #N/A, #VALUE!, #REF!, #DIV/0!, #NUM!, #NAME?, or #NULL!
