Integer

Validates if a value is an integer.

Installation

$ npm install validate.io-integer

For use in the browser, use browserify.

Usage

var isInteger = require( 'validate.io-integer' );

isInteger( value )

Validates if a value is an integer.

var value = 5;

var bool = isInteger( value );
// returns true

Note: this method validates that a value is numeric before determining if the value is an integer. For non-numeric values, the method returns false.

Examples

var bool;

bool = isInteger( 5 );
// returns true

bool = isInteger( 0 );
// returns true

bool = isInteger( 5.256 );
// returns false

bool = isInteger( 1/0 );
// returns false
