Usage
To use the module,
var deg2rad = ;
deg2rad( x )
Converts degrees to radians. x
may be either a numeric array
or a single numeric value.
// Single value:var rad = ;// returns pi/2// Array of values:var degs = 0 45 90 135 180 ;;// returns [ 0, pi/4, pi/2, 3pi/4, pi ]
Examples
var deg2rad = ;// Simulate some data...var data = 100 ;for var i = 0; i < datalength; i++data i = Math*360;;console;
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 180copy = data;;
If provided an empty array
, the function returns null
.
Tests
