Class BigDecimal

Method Summary
`void` | `downto(Number to, Closure closure)` Iterates from this number down to the given number, inclusive, decrementing by one each time.
`Number` | `multiply(Double right)` Multiply a BigDecimal and a Double.
`Number` | `multiply(BigInteger right)` Multiply a BigDecimal and a BigInteger.
`void` | `upto(Number to, Closure closure)` Iterates from this number up to the given number, inclusive, incrementing by one each time.

Method Detail

### downto

    public void downto(Number to, Closure closure)

  Iterates from this number down to the given number, inclusive, decrementing by one each time. Each number is passed to the closure. Example:

      10.5.downto(0) {
        println it
      }

  Prints numbers 10.5, 9.5 ... to 0.5.

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

Since:
  1.0

### multiply

    public Number multiply(Double right)

  Multiply a BigDecimal and a Double. Note: This method was added to enforce the Groovy rule of BigDecimal*Double == Double. Without this method, the multiply(BigDecimal) method in BigDecimal would respond and return a BigDecimal instead. Since BigDecimal is preferred over Number, the Number*Number method is not chosen as in older versions of Groovy.

Parameters:
  `right` - a Double.

Returns:
  the multiplication of left by right

Since:
  1.0

### multiply

    public Number multiply(BigInteger right)

  Multiply a BigDecimal and a BigInteger. Note: This method was added to enforce the Groovy rule of BigDecimal*long == long. Without this method, the multiply(BigDecimal) method in BigDecimal would respond and return a BigDecimal instead. Since BigDecimal is preferred over Number, the Number*Number method is not chosen as in older versions of Groovy. BigInteger is the fallback for all integer types in Groovy

Parameters:
  `right` - a BigInteger.

Returns:
  the multiplication of left by right

Since:
  1.0

### upto

    public void upto(Number to, Closure closure)

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

      0.1.upto( 10 ) {
        println it
      }

  Prints numbers 0.1, 1.1, 2.1... to 9.1

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

Since:
  1.0
