Package Exports

@stdlib/assert-is-integer

This package does not declare an exports field, so the exports above have been automatically detected and optimized by JSPM instead. If any package subpath is missing, it is recommended to post an issue to the original package (@stdlib/assert-is-integer) to support the "exports" field. If that is not possible, create a JSPM override to customize the exports field for this package.

Readme

isInteger

Test if a value is a number having an integer value.

Installation

npm install @stdlib/assert-is-integer

Usage

var isInteger = require( '@stdlib/assert-is-integer' );

isInteger( value )

Tests if a value is a number having an integer value.

var Number = require( '@stdlib/number-ctor' );

var bool = isInteger( 5.0 );
// returns true

bool = isInteger( new Number( 5.0 ) );
// returns true

bool = isInteger( -3.14 );
// returns false

bool = isInteger( null );
// returns false

isInteger.isPrimitive( value )

Tests if a value is a primitive number having an integer value.

var Number = require( '@stdlib/number-ctor' );

var bool = isInteger.isPrimitive( -3.0 );
// returns true

bool = isInteger.isPrimitive( new Number( -3.0 ) );
// returns false

isInteger.isObject( value )

Tests if a value is a Number object having an integer value.

var Number = require( '@stdlib/number-ctor' );

var bool = isInteger.isObject( 3.0 );
// returns false

bool = isInteger.isObject( new Number( 3.0 ) );
// returns true

Examples

var Number = require( '@stdlib/number-ctor' );
var isInteger = require( '@stdlib/assert-is-integer' );

var bool = isInteger( -5.0 );
// returns true

bool = isInteger( 0.0 );
// returns true

bool = isInteger( new Number( 5.0 ) );
// returns true

bool = isInteger( 5.256 );
// returns false

bool = isInteger( 1.0/0.0 );
// returns false

bool = isInteger( -1.0/0.0 );
// returns false

bool = isInteger( '5' );
// returns false

bool = isInteger( null );
// returns false
