isNegativeInteger

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

Usage

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

isNegativeInteger( value )

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

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

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

bool = isNegativeInteger( new Number( -5.0 ) );
// returns true

bool = isNegativeInteger( 5.0 );
// returns false

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

bool = isNegativeInteger( null );
// returns false

isNegativeInteger.isPrimitive( value )

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

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

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

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

isNegativeInteger.isObject( value )

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

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

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

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

Examples

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

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

bool = isNegativeInteger( new Number( -5.0 ) );
// returns true

bool = isNegativeInteger( 0.0 );
// returns false

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

bool = isNegativeInteger( 5.0 );
// returns false

bool = isNegativeInteger( '-5' );
// returns false

bool = isNegativeInteger( null );
// returns false
