Examples 
int val = 30;
 
void draw() {
  int t = timestwo(val);
  println(t);
}

int timestwo(int dVal) {
  dVal = dVal * 2;
  return dVal;
}
int[] vals = {10, 20, 30}; 
  
void draw() { 
  int[] t = timestwo(vals); 
  println(t); 
  noLoop();
} 
 
int[] timestwo(int[] dVals) { 
  for(int i = 0; i < dVals.length; i++) { 
    dVals[i] = dVals[i] * 2; 
  } 
  return dVals; 
}
void draw() {
  background(204);
  line(0, 0, width, height);
  if(mousePressed) {
    return;
  }
  line(0, height, width, 0);
}
Description Keyword used to indicate the value to return from a function. The value being returned must be the same datatype as defined in the function declaration. Functions declared with void can't return values and shouldn't include a return value. The keyword return may also be used to break out of a function thus not allowing the program to read the remaining statements (see the third example above).
Syntax 
type function {
  statements
  return value
}
Parameters
type boolean, byte, char, int, float, String, boolean[], byte[], char[], int[], float[], String[]
function a function that is being defined
statements any valid statements
value must be the same datatype as the type parameter
