Example If you enter the numbers 2; 3 and 4 in the Number 1; 2 and 3 text boxes, 9 will be returned as the result. =SUM(A1;A3;B5) calculates the sum of the three cells. =SUM (A1:E10) calculates the sum of all cells in the A1 to E10 cell range. Conditions linked by AND can be used with the function SUM() in the following manner: Example assumption: You have entered invoices into a table. Column A contains the date value of the invoice, column B the amounts. You want to find a formula that you can use to return the total of all amounts only for a specific month, e.g. only the amount for the period >=2008-01-01 to <2008-02-01. The range with the date values covers A1:A40, the range containing the amounts to be totaled is B1:B40. C1 contains the start date, 2008-01-01, of the invoices to be included and C2 the date, 2008-02-01, that is no longer included. Enter the following formula as an array formula: =SUM((A1:A40>=C1)*(A1:A40<C2)*B1:B40) In order to enter this as an array formula, you must press the Shift+Command + Ctrl+ Enter keys instead of simply pressing the Enter key to close the formula. The formula will then be shown in the Formula bar enclosed in braces. {=SUM((A1:A40>=C1)*(A1:A40<C2)*B1:B40)} The formula is based on the fact that the result of a comparison is 1 if the criterion is met and 0 if it is not met. The individual comparison results will be treated as an array and used in matrix multiplication, and at the end the individual values will be totaled to give the result matrix.

SUMIF function adding;specified numbers mw added one entry SUMIF Adds the cells specified by a given criteria. This function is used to browse a range when you search for a certain value.

If the criteria is written into the formula, it has to be surrounded by double quotes. SumRange is the range from which values are summed. If this parameter has not been indicated, the values found in the Range are summed. SUMIF supports the reference concatenation operator (~) only in the Criteria parameter, and only if the optional SumRange parameter is not given. Example To sum up only negative numbers: =SUMIF(A1:A10;"<0") =SUMIF(A1:A10;">0";B1:10) - sums values from the range B1:B10 only if the corresponding values in the range A1:A10 are >0.

Range is the range whose cells are included. Example You have a table in the cell range A1:B5 containing cities in column A and accompanying figures in column B. You have used an AutoFilter so that you only see rows containing the city Hamburg. You want to see the sum of the figures that are displayed; that is, just the subtotal for the filtered rows. In this case the correct formula would be: =SUBTOTAL(9;B2:B5)

Euro; converting EUROCONVERT function EUROCONVERTinsert link in financial Converts between old European national currency and to and from Euros. Syntax EUROCONVERT(Value; "From_currency"; "To_currency", full_precision, triangulation_precision) Value is the amount of the currency to be converted. From_currency and To_currency are the currency units to convert from and to respectively. These must be text, the official abbreviation for the currency (for example, "EUR"). The rates (shown per Euro) were set by the European Commission. Full_precision is optional. If omitted or False, the result is rounded according to the decimals of the To currency. If Full_precision is True, the result is not rounded. Triangulation_precision is optional. If Triangulation_precision is given and >=3, the intermediate result of a triangular conversion (currency1,EUR,currency2) is rounded to that precision. If Triangulation_precision is omitted, the intermediate result is not rounded. Also if To currency is "EUR", Triangulation_precision is used as if triangulation was needed and conversion from EUR to EUR was applied. Examples =EUROCONVERT(100;"ATS";"EUR") converts 100 Austrian Schillings into Euros. =EUROCONVERT(100;"EUR";"DEM") converts 100 Euros into German Marks.

CONVERT function CONVERT Converts a value from one unit of measurement to another unit of measurement. The conversion factors are given in a list in the configuration. At one time the list of conversion factors included the legacy European currencies and the Euro (see examples below). We suggest using the new function EUROCONVERT for converting these currencies. Syntax CONVERT(value;"text";"text") Example =CONVERT(100;"ATS";"EUR") returns the Euro value of 100 Austrian Schillings. =CONVERT(100;"EUR";"DEM") converts 100 Euros into German Marks.

FLOOR function rounding;down to nearest multiple of significance mw added one entry FLOOR Rounds a number down to the nearest multiple of Significance. Syntax FLOOR(Number; Significance; Mode) Number is the number that is to be rounded down. Significance is the value to whose multiple the number is to be rounded down. Mode is an optional value. If the Mode value is given and not equal to zero, and if Number and Significance are negative, then rounding is done based on the absolute value of the number. This parameter is ignored when exporting to MS Excel as Excel does not know any third parameter. If both parameters Number and Significance are negative, and if the Mode value is equal to zero or is not specified, then the results in $[officename] Calc and Excel will differ after exporting. If you export the spreadsheet to Excel, use Mode=1 to see the same results in Excel as in Calc. Example =FLOOR( -11;-2) returns -12 =FLOOR( -11;-2;0) returns -12 =FLOOR( -11;-2;1) returns -10see also CEILING, EVEN, ODD, MROUND, INT, TRUNC, ROUND, ROUNDDOWN, ROUNDUP,

MROUND function nearest multiple mw added one entry MROUND Returns a number rounded to the nearest multiple of another number.

COUNTIF function counting;specified cells mw added one entry COUNTIF Returns the number of cells that meet with certain criteria within a cell range.

Syntax COUNTIF(Range; Criteria) Range is the range to which the criteria are to be applied. Criteria indicates the criteria in the form of a number, an expression or a character string.

You may also indicate a cell range that contains the search criterion. If you search for literal text, enclose the text in double quotes. Example A1:A10 is a cell range containing the numbers 2000 to 2009. Cell B1 contains the number 2006. In cell B2, you enter a formula: =COUNTIF(A1:A10;2006) - this returns 1 =COUNTIF(A1:A10;B1) - this returns 1 =COUNTIF(A1:A10;">=2006") - this returns 4 =COUNTIF(A1:A10;"<"&B1) - when B1 contains 2006, this returns 6 =COUNTIF(A1:A10;C2) where cell C2 contains the text >2006 counts the number of cells in the range A1:A10 which are >2006 To count only negative numbers: =COUNTIF(A1:A10;"<0")
