- - ### Methods Detail

    - #### public double abs()

      Get the absolute value

      Returns:
        the absolute value of that Double
      Since:
        1.0

    - #### public boolean asBoolean()

      Coerce a Double instance to a boolean value.

      Returns:
        `true` for non-zero and non-NaN values, else `false`
      Since:
        2.6.0

    - #### public void downto(Number to, Closure closure)

      Iterates from this number down to the given number, inclusive, decrementing by one each time.

      Parameters:
        `to` - the end number
        `closure` - the code to execute for each number
      Since:
        1.0

    - #### public long round()

      Round the value

      Returns:
        the rounded value of that Double
      Since:
        1.0

    - #### public double round(int precision)

      Round the value

      Parameters:
        `precision` - the number of decimal places to keep
      Returns:
        the Double rounded to the number of decimal places specified by precision
      Since:
        1.6.4

    - #### public double trunc()

      Truncate the value

      Returns:
        the Double truncated to 0 decimal places
      Since:
        1.6.4

    - #### public double trunc(int precision)

      Truncate the value

      Parameters:
        `precision` - the number of decimal places to keep
      Returns:
        the Double truncated to the number of decimal places specified by precision
      Since:
        1.6.4

    - #### public void upto(Number to, Closure closure)

      Iterates from this number up to the given number, inclusive, incrementing by one each time.

      Parameters:
        `to` - the end number
        `closure` - the code to execute for each number
      Since:
        1.0
