isNonPositiveFinite

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

Usage

var isNonPositiveFinite = require( '@stdlib/assert/is-nonpositive-finite' );

isNonPositiveFinite( value )

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

var Number = require( '@stdlib/number/ctor' );
var NINF = require( '@stdlib/constants/float64/ninf' );

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

bool = isNonPositiveFinite( NINF );
// returns false

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

bool = isNonPositiveFinite( -3.14 );
// returns true

bool = isNonPositiveFinite( 5.0 );
// returns false

bool = isNonPositiveFinite( null );
// returns false

isNonPositiveFinite.isPrimitive( value )

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

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

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

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

isNonPositiveFinite.isObject( value )

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

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

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

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

Examples

var Number = require( '@stdlib/number/ctor' );
var isNonPositiveFinite = require( '@stdlib/assert/is-nonpositive-finite' );
var NINF = require( '@stdlib/constants/float64/ninf' );

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

bool = isNonPositiveFinite( NINF );
// returns false

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

bool = isNonPositiveFinite( 0.0 );
// returns true

bool = isNonPositiveFinite( -3.14 );
// returns true

bool = isNonPositiveFinite( 5.0 );
// returns false

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

bool = isNonPositiveFinite( null );
// returns false
