Issue regarding optical rotary encoder

Using Arduino Project Guidance
1 
#include <Encoder.h>

// Define the pins connected to the encoder
#define ENCODER_PIN_A 2
#define ENCODER_PIN_B 3

// Create an Encoder object
Encoder myEnc(ENCODER_PIN_A, ENCODER_PIN_B);

long oldPosition  = -999;

void setup() {
  // Start the serial communication
  Serial.begin(9600);
  Serial.println("Basic Encoder Test:");
}

void loop() {
  // Get the current position of the encoder
  long newPosition = myEnc.read();
  if (newPosition != oldPosition) {
    oldPosition = newPosition;
    // Print the new position to the serial monitor
    Serial.println(newPosition);
  }
}

Hey Experts,
I have a 360ppr rotary encoder when i use the basic code I've given above and rotate the encoder 360 degrees it gives out the value of 1440, whereas it should show 360, please help!
Thank you

360 * 4 = 1440, the lib counts every single change of pins 2/3 as a tick.
you can pretend you got encoder with 1440 ppr.
