isNonNegativeInteger
Test if a value is a number having a nonnegative integer value.
Installation
npm install @stdlib/assert-is-nonnegative-integer
Usage
var isNonNegativeInteger = require( '@stdlib/assert-is-nonnegative-integer' );
isNonNegativeInteger( value )
Tests if a value
is a number
having a nonnegative integer
value.
var Number = require( '@stdlib/number-ctor' );
var bool = isNonNegativeInteger( 5.0 );
bool = isNonNegativeInteger( new Number( 5.0 ) );
bool = isNonNegativeInteger( -5.0 );
bool = isNonNegativeInteger( 3.14 );
bool = isNonNegativeInteger( null );
isNonNegativeInteger.isPrimitive( value )
Tests if a value
is a primitive number
having a nonnegative integer
value.
var Number = require( '@stdlib/number-ctor' );
var bool = isNonNegativeInteger.isPrimitive( 3.0 );
bool = isNonNegativeInteger.isPrimitive( new Number( 3.0 ) );
isNonNegativeInteger.isObject( value )
Tests if a value
is a Number
object having a nonnegative integer
value.
var Number = require( '@stdlib/number-ctor' );
var bool = isNonNegativeInteger.isObject( 3.0 );
bool = isNonNegativeInteger.isObject( new Number( 3.0 ) );
Examples
var Number = require( '@stdlib/number-ctor' );
var isNonNegativeInteger = require( '@stdlib/assert-is-nonnegative-integer' );
var bool = isNonNegativeInteger( 5.0 );
bool = isNonNegativeInteger( new Number( 5.0 ) );
bool = isNonNegativeInteger( 0.0 );
bool = isNonNegativeInteger( 3.14 );
bool = isNonNegativeInteger( -5.0 );
bool = isNonNegativeInteger( '5' );
bool = isNonNegativeInteger( null );
