## Description
|
||
|
|
<section id='description'>
|
||
|
|
El operador <dfn>restante</dfn> <code>%</code> da el resto de la división de dos números.
|
||
|
|
<strong>Ejemplo</strong>
|
||
|
|
<blockquote>5 % 2 = 1 because<br>Math.floor(5 / 2) = 2 (Quotient)<br>2 * 2 = 4<br>5 - 4 = 1 (Remainder)</blockquote>
|
||
|
|
<strong>Usage</strong> <br> En matemáticas, se puede verificar que un número sea par o impar verificando el resto de la división del número entre <code>2</code> .
|
||
|
|
<blockquote>17 % 2 = 1 (17 is Odd)<br>48 % 2 = 0 (48 is Even)</blockquote>
|
||
|
|
<strong>Nota</strong> <br> El operador del <dfn>resto a</dfn> veces se denomina incorrectamente operador del "módulo". Es muy similar al módulo, pero no funciona correctamente con números negativos.
