deg2rad

Convert an angle from degrees to radians.

Usage

var deg2rad = require( '@stdlib/math/base/special/deg2rad' );

deg2rad( x )

Converts an angle from degrees to radians.

var r = deg2rad( 90.0 );
// returns ~1.571

r = deg2rad( -45.0 );
// returns ~-0.785

r = deg2rad( NaN );
// returns NaN

Examples

var randu = require( '@stdlib/random/base/randu' );
var deg2rad = require( '@stdlib/math/base/special/deg2rad' );

var d;
var r;
var i;

for ( i = 0; i < 100; i++ ) {
    d = (randu()*720.0) - 360.0;
    r = deg2rad( d );
    console.log( 'degrees: %d => radians: %d', d, r );
