			<h1>IRR Function</h1>
			<p>The <b>IRR</b> function is one of the financial functions. It is used to calculate the internal rate of return for a series of periodic cash flows.</p>
			<p>The <b>IRR</b> function syntax is:</p> 
			<p style="text-indent: 150px;"><b><em>IRR(values [,[guess]])</em></b></p> 
			<p><em>where</em></p> 
				<p style="text-indent: 50px;"><b><em>values</em></b> is an array that contains the series of payments occuring at regular periods. At least one of the values must be negative and at least one positive.</p> 
				<p style="text-indent: 50px;"><b><em>guess</em></b> is an estimate at what the internal rate of return will be. It is an optional argument. If it is omitted, the function will assume <b><em>guess</em></b> to be 10%.</p> 			
			<p>The numeric values can be entered manually or included into the cell you make reference to.</p>
			<p>To apply the <b>IRR</b> function,</p>
			<ol>
			<li>select the cell where you wish to display the result,</li>
			<li>click the <b>Insert function</b> <img alt="Insert function icon" src="../images/insertfunction.png" /> icon situated at the top toolbar,
				<br />or right-click within a selected cell and select the <b>Insert Function</b> option from the menu,
				<br />or click the <img alt="Function icon" src="../images/function.png" /> icon situated at the formula bar,
			</li>
			<li>select the <b>Financial</b> function group from the list,</li>
			<li>click the <b>IRR</b> function,</li>
			<li>enter the required arguments separating them by commas,</li>
			<li>press the <b>Enter</b> button.</li>
			</ol>
			<p>The result will be displayed in the selected cell.</p>
