- - ### Methods Detail

    - #### 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 Number power(Integer exponent)

      Power of a BigInteger to an integer certain exponent. If the exponent is positive, call the BigInteger.pow(int) method to maintain precision. Called by the '**' operator.

      Parameters:
        `exponent` - an Integer exponent
      Returns:
        a Number to the power of the exponent

    - #### public BigInteger power(BigInteger exponent)

      Power of a BigInteger to a BigInteger certain exponent. Called by the '**' operator.

      Parameters:
        `exponent` - a BigInteger exponent
      Returns:
        a BigInteger to the power of the exponent
      Since:
        2.3.8

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

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

          0.upto( 10 ) {
            println it
          }

      Prints numbers 0 to 10
      Parameters:
        `to` - the end number
        `closure` - the code to execute for each number
      Since:
        1.0
