isPositiveZero
Test if a value is a number equal to positive zero.
Usage
var isPositiveZero = require( '@stdlib/assert/is-positive-zero' );
isPositiveZero( value )
Tests if a value
is a number
having a value equal to positive zero.
var Number = require( '@stdlib/number/ctor' );
var bool = isPositiveZero( 0.0 );
// returns true
bool = isPositiveZero( new Number( 0.0 ) );
// returns true
bool = isPositiveZero( -3.14 );
// returns false
bool = isPositiveZero( -0.0 );
// returns false
bool = isPositiveZero( null );
// returns false
isPositiveZero.isPrimitive( value )
Tests if a value
is a primitive number
equal to positive zero.
var Number = require( '@stdlib/number/ctor' );
var bool = isPositiveZero.isPrimitive( 0.0 );
// returns true
bool = isPositiveZero.isPrimitive( new Number( 0.0 ) );
// returns false
isPositiveZero.isObject( value )
Tests if a value
is a Number
object having a value equal to positive zero.
var Number = require( '@stdlib/number/ctor' );
var bool = isPositiveZero.isObject( 0.0 );
// returns false
bool = isPositiveZero.isObject( new Number( 0.0 ) );
// returns true
Examples
