r: the radial coordinate r, (float)

phi: the angular coordinate phi, (float)

Returns

Nothing

Example

#include <Coordinates.h>
Coordinates point = Coordinates();
void setup() {
  Serial.begin(9600);
  float r = 1.41;
  float phi = 3.14159 / 4; // angle = pi / 4 radians
  Serial.print("r: ");
  Serial.println(r);
  Serial.print("φ: ");
  Serial.println(phi);
  Serial.println(" rad");
  point.fromPolar(r, phi);
  Serial.print("x: ");
  Serial.println(point.getX());
  Serial.print("y: ");
  Serial.print(point.getY());
}

void loop() {}
