5.5 % 2 // 1.5
</pre>

<h2 id="Exponentiation" name="Exponentiation">Üs (**)</h2>

<p>The exponentiation operator returns the result of raising first operand to the power second operand. That is, <code>var1</code><sup><code>var2</code></sup>, in the preceding statement, where <code>var1</code> and <code>var2</code> are variables. Exponentiation operator is right associative. <code>a ** b ** c</code> is equal to <code>a ** (b ** c)</code>.</p>

<h3 id="Syntax_2">Syntax</h3>

<pre class="syntaxbox"><strong>Operator:</strong> var1 ** var2
</pre>

<h3 id="Notes">Notes</h3>

<p>In most languages like PHP and Python and others that have an exponentiation operator (**), the exponentiation operator is defined to have a higher precedence than unary operators such as unary + and unary -, but there are a few exceptions. For example, in Bash the ** operator is defined to have a lower precedence than unary operators. In JavaScript, it is impossible to write an ambiguous exponentiation expression, i.e. you cannot put a unary operator (<code>+/-/~/!/delete/void/typeof</code>) immediately before the base number.</p>

<pre class="brush: js">-2 ** 2;
// 4 in Bash, -4 in other languages.
// This is invalid in JavaScript, as the operation is ambiguous.


-(2 ** 2);
// -4 in JavaScript and the author's intention is unambiguous.
</pre>

<h3 id="Examples_2">Examples</h3>

<pre class="brush: js">2 ** 3 // 8
3 ** 2 // 9
3 ** 2.5 // 15.588457268119896
10 ** -1 // 0.1
NaN ** 2 // NaN

2 ** 3 ** 2 // 512
2 ** (3 ** 2) // 512
(2 ** 3) ** 2 // 64
</pre>

<p>To invert the sign of the result of an exponentiation expression:</p>

<pre class="brush: js">-(2 ** 2) // -4
</pre>

<p>To force the base of an exponentiation expression to be a negative number:</p>

<pre class="brush: js">(-2) ** 2 // 4
</pre>

<div class="note">
<p><strong>Note:</strong> JavaScript also has <a href="/en-US/docs/Web/JavaScript/Reference/Operators/Bitwise_Operators#Bitwise_XOR">a bitwise operator ^ (logical XOR)</a>. <code>**</code> and <code>^</code> are different (for example : <code>2 ** 3 === 8</code> when <code>2 ^ 3 === 1</code>.)</p>
</div>

<h2 id="Increment" name="Increment">Artırma (++)</h2>

<p>Artış operatörü işlenenini artırır (bir ekler) ve bir değer döndürür.</p>

<ul>
 <li>İlk önce değişken adı kullanılırsa, değişkenden sonra operatörle (örneğin, x++) kullanılırsa artmadan önce değeri artırır ve döndürür.</li>
 <li>Ön ek kullanılırsa, değişkenden önce operatörle (örneğin, ++x), daha sonra artırıldıktan sonra değeri artıtrır ve döndürür.</li>
</ul>

<h3 id="Söz_Dizimi_5">Söz Dizimi</h3>

<pre class="syntaxbox"><strong>Operator:</strong> x++ yada ++x
</pre>

<h3 id="Örnekler_5">Örnekler</h3>

<pre class="brush: js">// Postfix
var x = 3;
y = x++; // y = 3, x = 4

// Prefix
var a = 2;
b = ++a; // a = 3, b = 3
</pre>

<h2 id="Decrement" name="Decrement">Azaltma (--)</h2>

<p>The decrement operator decrements (subtracts one from) its operand and returns a value.</p>

<ul>
 <li>If used postfix, with operator after operand (for example, x--), then it decrements and returns the value before decrementing.</li>
 <li>If used prefix, with operator before operand (for example, --x), then it decrements and returns the value after decrementing.</li>
</ul>

<h3 id="Syntax_3">Syntax</h3>

<pre class="syntaxbox"><strong>Operator:</strong> x-- or --x
</pre>

<h3 id="Examples_3">Examples</h3>

<pre class="brush: js">// Postfix
var x = 3;
y = x--; // y = 3, x = 2

// Prefix
var a = 2;
b = --a; // a = 1, b = 1
</pre>

<h2 id="Unary_negation" name="Unary_negation">Unary negation (-)</h2>

<p>The unary negation operator precedes its operand and negates it.</p>

<h3 id="Syntax_4">Syntax</h3>

<pre class="syntaxbox"><strong>Operator:</strong> -x
</pre>

<h3 id="Examples_4">Examples</h3>

<pre class="brush: js">var x = 3;
y = -x; // y = -3, x = 3

// Unary negation operator can convert non-numbers into a number
var x = "4";
y = -x; // y = -4
</pre>

<h2 id="Unary_plus_2"><a name="Unary_plus">Unary plus</a> (+)</h2>

<p>The unary plus operator precedes its operand and evaluates to its operand but attempts to convert it into a number, if it isn't already. Although unary negation (-) also can convert non-numbers, unary plus is the fastest and preferred way of converting something into a number, because it does not perform any other operations on the number. It can convert string representations of integers and floats, as well as the non-string values <code>true</code>, <code>false</code>, and <code>null</code>. Integers in both decimal and hexadecimal ("0x"-prefixed) formats are supported. Negative numbers are supported (though not for hex). If it cannot parse a particular value, it will evaluate to {{jsxref("NaN")}}.</p>

<h3 id="Syntax_5">Syntax</h3>

<pre class="syntaxbox"><strong>Operator:</strong> +x
</pre>

<h3 id="Examples_5">Examples</h3>

<pre class="brush: js">+3     // 3
+'3'   // 3
+true  // 1
+false // 0
+null  // 0
+function(val){ return val } // NaN
</pre>
