Methods Detail

• 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

• 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

• 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

• public Number power(Integer exponent)

  Power of a BigDecimal to an integer certain exponent. If the exponent is positive, call the BigDecimal.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

• 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
