    NPM version Build Status Coverage Status dependencies

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

    Installation

    npm install @stdlib/assert-is-nonpositive-integer

    Usage

    var isNonPositiveInteger = require( '@stdlib/assert-is-nonpositive-integer' );

    isNonPositiveInteger( value )

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

    var Number = require( '@stdlib/number-ctor' );
    
    var bool = isNonPositiveInteger( -5.0 );
    // returns true
    
    bool = isNonPositiveInteger( new Number( -5.0 ) );
    // returns true
    
    bool = isNonPositiveInteger( 5.0 );
    // returns false
    
    bool = isNonPositiveInteger( -3.14 );
    // returns false
    
    bool = isNonPositiveInteger( null );
    // returns false

    isNonPositiveInteger.isPrimitive( value )

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

    var Number = require( '@stdlib/number-ctor' );
    
    var bool = isNonPositiveInteger.isPrimitive( -3.0 );
    // returns true
    
    bool = isNonPositiveInteger.isPrimitive( new Number( -3.0 ) );
    // returns false

    isNonPositiveInteger.isObject( value )

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

    var Number = require( '@stdlib/number-ctor' );
    
    var bool = isNonPositiveInteger.isObject( -3.0 );
    // returns false
    
    bool = isNonPositiveInteger.isObject( new Number( -3.0 ) );
    // returns true

    Examples

    var Number = require( '@stdlib/number-ctor' );
    var isNonPositiveInteger = require( '@stdlib/assert-is-nonpositive-integer' );
    
    var bool = isNonPositiveInteger( -5.0 );
    // returns true
    
    bool = isNonPositiveInteger( new Number( -5.0 ) );
    // returns true
    
    bool = isNonPositiveInteger( 0.0 );
    // returns true
    
    bool = isNonPositiveInteger( -3.14 );
    // returns false
    
    bool = isNonPositiveInteger( 5.0 );
    // returns false
    
    bool = isNonPositiveInteger( '-5' );
    // returns false
    
    bool = isNonPositiveInteger( null );
    // returns false
