For use in the browser, use browserify.
Usage
To use the module,
var deg2rad = require( 'compute-deg2rad' );
deg2rad( x )
Converts degrees to radians. x
may be either a numeric array
or a single numeric value.
var rad = deg2rad( 90 );
var degs = [ 0, 45, 90, 135, 180 ];
deg2rad( degs );
Examples
var deg2rad = require( 'compute-deg2rad' );
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,
$ node ./examples/index.js
Notes
If provided an input array
, the array
is mutated. If mutation is undesired,
var data = [ 0, 45, 90, 135, 180 ],
copy = data.slice();
deg2rad( copy );
If provided an empty array
, the function returns null
.
Tests
Unit
Unit tests use the Mocha test framework with Chai assertions. To run the tests, execute the following command in the top-level application directory:
$ make test
All new feature development should have corresponding unit tests to validate correct functionality.
Test Coverage
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:
$ make test-cov
Istanbul creates a ./reports/coverage
directory. To access an HTML version of the report,
