        <title>Description</title>
        <para>ACCRINT calculates the accrued interest for a security that pays periodic interest.  @issue is the issue date of the security.  @first_interest is the first interest date of the security.  @settlement is the settlement date of the sequrity.  The settlement date is always after the issue date (the date when the security is bought). @rate is the annual rate of the security and @par is the par value of the security. @frequency is the number of coupon payments per year. Allowed frequencies are: 1 = annual, 2 = semi, 4 = quarterly. @basis is the type of day counting system you want to use:</para>

The dates must be @issue &lt; @first_interest &lt; @settlement, or ACCRINT returns #NUM! error. If @rate &lt;= 0 or @par &lt;= 0 , ACCRINT returns #NUM! error. If @basis is omitted, US 30/360 is applied. If @basis &lt; 0 or @basis &gt; 4, ACCRINT returns #NUM! error. If @issue date is after @settlement date or they are the same, ACCRINT returns #NUM! error.</para>

        <para>@database is a range of cells in which rows of related information are records and columns of data are fields. The first row of a database contains labels for each column.</para>        <para>@field specifies which column is used in the function.  If @field is an integer, for example. 2, the second column is used. Field can also be the label of a column.  For example, ``Age'' refers to the column with the label ``Age'' in @database range.</para>        <para>@criteria is the range of cells which contains the specified conditions.  The first row of a @criteria should contain the labels of the fields for which the criterias are for.  Cells below the labels specify conditions, for example, ``&gt;3'' or ``&lt;9''.  Equality condition can be given simply by specifing a value, e.g. ``3'' or ``John''.  Each row in @criteria specifies a separate condition, i.e. if a row in @database matches with one of the rows in @criteria then that row is counted in (technically speaking boolean OR between the rows in @criteria).  If @criteria specifies more than one columns then each of the conditions in these columns should be true that the row in @database matches (again technically speaking boolean AND between the columns in each row in @criteria).</para>

For example, ``Age'' refers to the column with the label ``Age'' in @database range.</para>        <para>@criteria is the range of cells which contains the specified conditions.  The first row of a @criteria should contain the labels of the fields for which the criterias are for.  Cells below the labels specify conditions, for example, ``&gt;3'' or ``&lt;9''.  Equality condition can be given simply by specifing a value, e.g. ``3'' or ``John''.  Each row in @criteria specifies a separate condition, i.e. if a row in @database matches with one of the rows in @criteria then that row is counted in (technically speaking boolean OR between the rows in @criteria).  If @criteria specifies more than one columns then each of the conditions in these columns should be true that the row in @database matches (again technically speaking boolean AND between the columns in each row in @criteria).</para>

        <para>@database is a range of cells in which rows of related information are records and columns of data are fields. The first row of a database contains labels for each column.</para>        <para>@field specifies which column is used in the function.  If @field is an integer, for example. 2, the second column is used. Field can also be the label of a column.  For example, ``Age'' refers to the column with the label ``Age'' in @database range.</para>        <para>@criteria is the range of cells which contains the specified conditions.  The first row of a @criteria should contain the labels of the fields for which the criterias are for.  Cells below the labels specify conditions, for example, ``&gt;3'' or ``&lt;9''.  Equality condition can be given simply by specifing a value, e.g. ``3'' or ``John''.  Each row in @criteria specifies a separate condition, i.e. if a row in @database matches with one of the rows in @criteria then that row is counted in (technically speaking boolean OR between the rows in @criteria).  If @criteria specifies more than one columns then each of the conditions in these columns should be true that the row in @database matches (again technically speaking boolean AND between the columns in each row in @criteria).</para>

        <title>Description</title>
        <para>LINEST function calculates the ``least squares'' line that best fit to your data in @known_y's.  @known_x's contains the corresponding x's where y=mx+b.</para>
        <para>If @known_x's is omitted, an array {1, 2, 3, ...} is used. LINEST returns an array having two columns and one row.  The slope (m) of the regression line y=mx+b is given in the first column and the y-intercept (b) in the second.</para>        <para>If @known_y's and @known_x's have unequal number of data points, LINEST returns #NUM! error.</para>        <para>If @const is FALSE, the line will be forced to go through the origin, i.e., b will be zero. The default is TRUE.</para>        <para>If @stat is TRUE, extra statistical information will be returned. Extra statistical information is written bellow the regression line coefficients in the result array.  Extra statistical information consists of four rows of data.  In the first row the standard error values for the coefficients m1, (m2, ...), b are represented.  The second row contains the square of R and the standard error for the y estimate.  The third row contains the F-observed value and the degrees of freedom.  The last row contains the regression sum of squares and the residual sum of squares.</para>        <para>The default of @stat is FALSE.</para>

        <para>SLN function will determine the straight line depreciation of an asset for a single period. The amount you paid for the asset is the @cost, @salvage is the value of the asset at the end of its useful life, and @life is the number of periods over which an the asset is depreciated. This method of deprecition devides the cost evenly over the life of an asset.</para>
        <para>The formula used for straight line depriciation is:</para>        <para>Depriciation expense = ( @cost - @salvage_value ) / @life</para>        <para>	@cost = cost of an asset when acquired (market value).	@salvage_value = amount you get when asset sold at the end of the assets's useful life.	@life = anticipated life of an asset.</para>

        <para>For example, lets suppose your company purchases a new machine for $10,000, which has a salvage value of $700 and will have a useful life of 10 years. The SLN yearly depreciation is computed as follows:</para>        <para>=SLN(10000, 700, 10)</para>        <para>This will return the yearly depreciation figure of $930.</para>

        <para>SYD function calculates the sum-of-years digits depriciation for an asset based on its cost, salvage value, anticipated life and a particular period. This method accelerates the rate of the depreciation, so that more depreciation expense occurs in earlier periods than in later ones. The depreciable cost is the actual cost minus the salvage value. The useful life is the number of periods (typically years) over with the asset is depreciated.</para>
        <para>The Formula used for sum-of-years digits depriciation is:</para>        <para>Depriciation expense = ( @cost - @salvage_value ) * (@life - @period + 1) * 2 / @life * (@life + 1).</para>        <para>	@cost = cost of an asset when acquired (market value).	@salvage_value = amount you get when asset sold at the end of its useful life.	@life = anticipated life of an asset.	@period = period for which we need the expense.</para>

        <title>Description</title>
        <para>XIRR calculates and returns the internal rate of return of an investment that has not necessarily periodic payments.  This function is closely related to the net present value function (NPV and XNPV).  The XIRR is the interest rate for a serie of cash flow where the XNPV is zero.</para>
        <para>@values contains the serie of cash flow generated by the investment.  @dates contains the dates of the payments.  The first date describes the payment day of the initial payment and thus all the other dates should be after this date. The optional @guess is the initial value used in calculating the XIRR.  You do not have to use that, it is only provided for the Excel compatibility.</para>        <para>This function is Excel compatible.</para>
