Package Exports

@stdlib/math-base-special-rad2deg

This package does not declare an exports field, so the exports above have been automatically detected and optimized by JSPM instead. If any package subpath is missing, it is recommended to post an issue to the original package (@stdlib/math-base-special-rad2deg) to support the "exports" field. If that is not possible, create a JSPM override to customize the exports field for this package.

Readme

rad2deg

$NPM version$ $Build Status$ $Coverage Status$ $dependencies$

Convert an angle from radians to degrees.

Installation

npm install @stdlib/math-base-special-rad2deg

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 );
}

Notice

This package is part of stdlib, a standard library for JavaScript and Node.js, with an emphasis on numerical and scientific computing. The library provides a collection of robust, high performance libraries for mathematics, statistics, streams, utilities, and more.
