Validates if a value is an integer.
Installation

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
