<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>
<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>
