Convert Degrees To Radians And Radians To Degrees

var degrees = 90;

var radians = degreesToRadians(degrees); 
degrees = radiansToDegrees(radians);

trace(radians); //Outputs 1.57
trace(degrees); //Outputs 90

function degreesToRadians(degrees:Number):Number {
 return degrees * Math.PI / 180;
}

function radiansToDegrees(radians:Number):Number{
 return radians * 180 / Math.PI;
}
