> Converts degrees to radians.
`` bash`
$ npm install compute-deg2rad
For use in the browser, use browserify.
To use the module,
` javascript`
var deg2rad = require( 'compute-deg2rad' );
#### deg2rad( x )
Converts degrees to radians. x may be either a numeric array or a single numeric value.
` javascript
// Single value:
var rad = deg2rad( 90 );
// returns pi/2
// Array of values:
var degs = [ 0, 45, 90, 135, 180 ];
deg2rad( degs );
// returns [ 0, pi/4, pi/2, 3pi/4, pi ]
`
` javascript
var deg2rad = require( 'compute-deg2rad' );
// Simulate some data...
var data = new Array( 100 );
for ( var i = 0; i < data.length; i++ ) {
data[ i ] = Math.random()*360;
}
deg2rad( data );
console.log( data.join( '\n' ) );
`
To run the example code from the top-level application directory,
` bash`
$ node ./examples/index.js
If provided an input array, the array is mutated. If mutation is undesired,
` javascript
var data = [ 0, 45, 90, 135, 180 ],
copy = data.slice();
deg2rad( copy );
`
If provided an empty array, the function returns null.
Unit tests use the Mocha test framework with Chai assertions. To run the tests, execute the following command in the top-level application directory:
` bash`
$ make test
All new feature development should have corresponding unit tests to validate correct functionality.
This repository uses Istanbul as its code coverage tool. To generate a test coverage report, execute the following command in the top-level application directory:
` bash`
$ make test-cov
Istanbul creates a ./reports/coverage directory. To access an HTML version of the report,
` bash``
$ make view-cov
