CompositeNumber
protected CompositeNumber(int sign,
java.lang.String asString)
throws java.lang.IllegalArgumentException
- Constructs a new
CompositeNumber
object.
The sign of the value needs to be specified. Any negative value is
interpreted as meaning that the value of this number is negative. Any
positive value is interpreted as meaning that the value of this number
is positive.
- Parameters:
sign
- the sign of this number, either a positive number if the number is
greater than zero, 0 if the number equals zero or a negative number
if the number is smaller than zero.asString
- a textual presentation of this number, not null
.
- Throws:
java.lang.IllegalArgumentException
- if asString == null
.
getElements
public abstract RealNumber[] getElements()
- Returns the operands.
- Returns:
- a new array, containing the operands.
getElementCount
public abstract int getElementCount()
- Counts the number of operands.
- Returns:
- the operand count, >= 0.
getElement
public abstract RealNumber getElement(int n)
throws java.lang.IndexOutOfBoundsException
- Returns the nth operand.
- Parameters:
n
- the index of the operand, >= 0 and <
getElementCount()
.
- Returns:
- the nth operand, not
null
.
- Throws:
java.lang.IndexOutOfBoundsException
- if one of the following applies:
n < 0
n >= operandCount
