isInteger

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

## Usage

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

isInteger( value )

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

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

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

isInteger.isIntegerArray( value )

Tests if a value is a number array having only integer values.

var bool = isInteger.isIntegerArray( [ -3.0, new Number(3.0) ] );
// returns true

bool = isInteger.isIntegerArray( [ 3.0, '-3.0' ] );
// returns false

isInteger.isPrimitiveIntegerArray( value )

Tests if a value is a primitive number array having only integer values.

var bool = isInteger.isPrimitiveIntegerArray( [ 1.0, -1.0 ] );
// returns true

bool = isInteger.isPrimitiveIntegerArray( [ 3.0, new Number(-1.0) ] );
// returns false

## Examples

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

console.log( isInteger( -5.0 ) );
// returns true

console.log( isInteger( 0.0 ) );
// returns true

console.log( isInteger( new Number( 5.0 ) ) );
// returns true

console.log( isInteger( 5.256 ) );
// returns false

console.log( isInteger( 1.0/0.0 ) );
// returns false

console.log( isInteger( -1.0/0.0 ) );
// returns false

console.log( isInteger( '5' ) );
// returns false

console.log( isInteger( null ) );
// returns false
