rad2deg
Convert an angle from radians to degrees.
Usage
var rad2deg = require( '@stdlib/math/base/special/rad2deg' );
rad2deg( x )
Converts an angle from radians to degrees.
var d = rad2deg( 3.141592653589793/2.0 );
// returns 90.0
d = rad2deg( -3.141592653589793/4.0 );
// returns -45.0
d = rad2deg( NaN );
// returns NaN
Notes
-
Due to finite precision, canonical values may not be returned. For example,
var d = rad2deg( 3.141592653589793/6.0 ); // returns 29.999999999999996
Examples
var randu = require( '@stdlib/random/base/randu' );
var TWO_PI = require( '@stdlib/constants/float64/two-pi' );
var rad2deg = require( '@stdlib/math/base/special/rad2deg' );
var r;
var d;
var i;
for ( i = 0; i < 100; i++ ) {
r = randu() * TWO_PI;
d = rad2deg( r );
console.log( 'radians: %d => degrees: %d', r, d );
