<h1>SIGN Function</h1>
|
|||
|
|
<p>The <b>SIGN</b> function is one of the math and trigonometry functions. It is used to return the sign of a number. If the number is positive, the function returns <b>1</b>. If the number is negative, the function returns <b>-1</b>. If the number is <b>0</b>, the function returns <b>0</b>.</p>
|
|||
|
|
<p>The <b>SIGN</b> function syntax is:</p>
|
|||
|
|
<p style="text-indent: 150px;"><b><em>SIGN(number)</em></b></p>
|
|||
|
|
<p>where <b><em>number</em></b> is a numeric value entered manually or included into the cell you make reference to.</p>
|
|||
|
|
<p>To apply the <b>SIGN</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>Math and trigonometry</b> function group from the list,</li>
|
|||
|
|
<li>click the <b>SIGN</b> function,</li>
|
|||
|
|
<li>enter the required argument,</li>
|
|||
|
|
<li>press the <b>Enter</b> button.</li>
|
|||
|
|
</ol>
|
|||
|
|
<p>The result will be displayed in the selected cell.</p>
|
|||
|
|
<p><em>For example:</em></p>
|
|||
|
|
<p>The required argument is <b>A1</b>, where <b>A1</b> is <b>12</b>. The number is positive, so the function returns <b>1</b>.</p>
|
|||
|
|
<p style="text-indent: 150px;"><img alt="SIGN Function: POSITIVE" src="../images/signpositive.png" /></p>
|
|||
|
|
<p>If we change the <b>A1</b> value from <b>12</b> to <b>-12</b>, the function returns <b>-1</b>:</p>
|
|||
|
|
<p style="text-indent: 150px;"><img alt="SIGN Function: NEGATIVE" src="../images/signnegative.png" /></p>
