This library was generated with [Angular CLI](https://github.com/angular/angular-cli) version 7.2.0.

> Note: This library is currently a work in progress and is therefore subject to frequent changes. Use with care. 

## Installation

Run `npm install --save @cabinfo.eu/astrophysics-library` to install the library.

## Objects

For the moment, the library contains only one object. This object exposes physical constants and physical quantities as well as conversion methods.

### Example

````typescript
    let physicsConstants = new CPhysicsConstants();
    physicsConstants.logConstants();
    console.info( 'Light celerity in vaccum  : ', physicsConstants.c );
    console.info( 'Ligth celerity informations : ', physicsConstants.getConstantInfo( 'c' ) );
    console.info( 'Ligth celerity unit : ', physicsConstants.getConstantInfo( 'c' ).unit );
    console.info( '******************************************************************************************' );
    console.info( 'Convert 1.49597870e11 meter to astronomical unit : ', physicsConstants.meter2au( 1.49597870e11 ) );
    console.info( 'Convert 3.085677581e16 meter to parsec : ', physicsConstants.meter2pc( 3.085677581e16 ) );
    console.info( 'Convert 9460730472580800 meter to light year : ', physicsConstants.meter2lr( 9460730472580800 ) );
    console.info( 'Convert 1 astronomical unit to meter : ', physicsConstants.au2meter( 1 ) );
    console.info( 'Convert 1 astronomical unit to kilometer : ', physicsConstants.au2kilometer( 1 ) );
