About stdlib...

We believe in a future in which the web is a preferred environment for numerical computation. To help realize this future, we've built stdlib. stdlib is a standard library, with an emphasis on numerical and scientific computation, written in JavaScript (and C) for execution in browsers and in Node.js.

The library is fully decomposable, being architected in such a way that you can swap out and mix and match APIs and functionality to cater to your exact preferences and use cases.

When you use stdlib, you can be absolutely certain that you are using the most thorough, rigorous, well-written, studied, documented, tested, measured, and high-quality code out there.

To join us in bringing numerical computing to the web, get started by checking us out on GitHub, and please consider financially supporting stdlib. We greatly appreciate your continued support!

isPositiveFinite

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

Installation

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

Usage

var isPositiveFinite = require( '@stdlib/assert-is-positive-finite' );

isPositiveFinite( value )

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

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

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

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

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

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

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

bool = isPositiveFinite( null );
// returns false

isPositiveFinite.isPrimitive( value )

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

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

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

bool = isPositiveFinite.isPrimitive( 3.0/0.0 );
// returns false

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

isPositiveFinite.isObject( value )

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

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

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

bool = isPositiveFinite.isObject( 3.0 );
// returns false

bool = isPositiveFinite.isObject( new Number( 1.0/0.0 ) );
// returns false

Examples

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

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

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

bool = isPositiveFinite( 3.14 );
// returns true

bool = isPositiveFinite( 0.0 );
// returns false

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

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

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

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

bool = isPositiveFinite( null );
// returns false
