float deg = degrees(rad);
Serial.print(" radians is ");
||Converts a radian measurement to its corresponding value in degrees. Radians and degrees are two ways of measuring the same thing. There are 360 degrees in a circle and 2*PI radians in a circle. For example, 90° = PI/2 = 1.5707964. All trigonometric methods in Wiring require their parameters to be specified in radians.
