  @Devillord234 -- Note that casting to float also works, but precision differs between Double.toString(d), text(float(d),x,y), and println((float)d):

  size(200, 150);
  double d = Math.E;
  text(Double.toString(d), 10, 20); // 2.718281828459045
  println(Double.toString(d));      // 2.718281828459045
  text((float)d, 10, 40);           // 2.718
  println((float)d);                // 2.7182817
