isNonNegativeFinite

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

Installation

npm install @stdlib/assert-is-nonnegative-finite

Usage

var isNonNegativeFinite = require( '@stdlib/assert-is-nonnegative-finite' );

isNonNegativeFinite( value )

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

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

var bool = isNonNegativeFinite( 5.0 );
// returns true

bool = isNonNegativeFinite( new Number( 5.0 ) );
// returns true

bool = isNonNegativeFinite( 3.14 );
// returns true

bool = isNonNegativeFinite( -5.0 );
// returns false

bool = isNonNegativeFinite( null );
// returns false

bool = isNonNegativeFinite( 1.0/0.0 );
// returns false

isNonNegativeFinite.isPrimitive( value )

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

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

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

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

isNonNegativeFinite.isObject( value )

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

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

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

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

Examples

var Number = require( '@stdlib/number-ctor' );
var isNonNegativeFinite = require( '@stdlib/assert-is-nonnegative-finite' );

var bool = isNonNegativeFinite( 5.0 );
// returns true

bool = isNonNegativeFinite( new Number( 5.0 ) );
// returns true

bool = isNonNegativeFinite( new Number( 1.0/0.0 ) );
// returns false

bool = isNonNegativeFinite( 1.0/0.0 );
// returns false

bool = isNonNegativeFinite( 0.0 );
// returns true

bool = isNonNegativeFinite( 3.14 );
// returns true

bool = isNonNegativeFinite( -5.0 );
// returns false

bool = isNonNegativeFinite( '5' );
// returns false

bool = isNonNegativeFinite( null );
// returns false
