Feature details

Feature description

In many programs a value starts again at zero if it gets larger than a max value or appears at max value when it goes below zero. Provide a function that does the wrapping as a single function.

  /**
   * Wraps a value at 0 and max to constrain value between zero and max.
   * @param value The value to wrap
   * @param max The maximum value (excluded)
   * @return The toroidally wrapped value
  float wrap(float value, float max) {
    if (value < 0) {
      return value + max;
    } else if (value >= max) {
      return value - max;
    }
    return value;
  }

Benefits

This would reduce code sizes and make these toroidal worlds easier to understand.

Empieza localizando los puntos de entrada matemáticos existentes de la biblioteca principal de Processing y cualquier lógica de wrap relacionada. Define la función de wrap toroidal descrita en la issue y después añade o actualiza la cobertura de pruebas para valores por debajo de cero, valores iguales o superiores al máximo y valores que ya están dentro del rango.
