Method Summary
`long` | `abs()` Get the absolute value
`void` | `downto(Number to, Closure closure)` Iterates from this number down to the given number, inclusive, decrementing by one each time.

`void` | `upto(Number to, Closure closure)` Iterates from this number up to the given number, inclusive, incrementing by one each time.

Method Detail

### abs

    public long abs()

  Get the absolute value

Returns:
  the absolute value of that Long

Since:
  1.0

### downto

    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

### power

    public Number power(Integer exponent)

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

Parameters:
  `exponent` - an Integer exponent.

Returns:
  a Number to the power of a the exponent

### upto

    public void upto(Number to, Closure closure)
