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

Examples

var isInteger = require( '@stdlib/utils/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
