<p>The <b>IF</b> function is one of the logical functions. Is used to check the logical expression and return one value if it is TRUE, or another if it is FALSE.</p>
<p>where <b><em>logical_test</em></b>, <b><em>value_if_true</em></b>, <b><em>value_if_false</em></b> are values entered manually or included into the cell you make reference to.</p>
<p>To apply the <b>IF</b> function,</p>
<ol>
<li>select the cell where you wish to display the result,</li>
<li>click the <b>Insert Function</b><imgalt="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 <imgalt="Function icon"src="../images/function.png"/> icon situated at the formula bar,
</li>
<li>select the <b>Logical</b> function group from the list,</li>
<li>click the <b>IF</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>
<p>There are three arguments: <em>logical_test</em> = <b>A1<100</b>, <em>value_if_true</em> = <b>0</b>, <em>value_if_false</em> = <b>1</b>, where <b>A1</b> is <b>12</b>. This logical expression is <b>TRUE</b>. So the function returns <b>0</b>.</p>
