public class RARandomReal
extends RAReal
implements java.io.Serializable

Class RARandomReal represents a random real (double precision number x with 0<=x<1) in the RAAR environment. Every time you request this random's dValue, a different random number is returned. You can store the num- ber in an ordinary RAReal to have a persistent value.

Method Detail

value

public RADataType value()
                 throws RAException

Return this object (for compatibility with RADataType).

Specified by:

value in interface RAAssignable

Specified by:

value in interface RAMathObject

Overrides:

value in class RAReal

Returns:

Duh...

Throws:

RAException

dValue

public double dValue()
              throws RAException

Return a new random value between 0 inclusive and 1 exclusive.

Overrides:

dValue in class RAReal

Returns:

Duh...

Throws:

RAException

toString

public java.lang.String toString()

String representation of this real.

Overrides:

toString in class RAReal

equals

public boolean equals(RAEqualityComparable otherMathObject)
               throws RAException

Returns true if this real is equal to the parameter. Overridden to return false since the value is dynamic.

Specified by:

equals in interface RAEqualityComparable

Overrides:

equals in class RAReal

Parameters:

a - real...

Returns:

true or false

Throws:

RAException

larger

public boolean larger(RAFullComparable r)
               throws RAException

Returns true if this real is larger than r. Overridden to return false since the value is dynamic.

Specified by:

larger in interface RAFullComparable

Overrides:

larger in class RAReal

Parameters:

r - Another real bites the dust

Returns:

true or false, see above.

Throws:

RAException

smaller

public boolean smaller(RAFullComparable r)
                throws RAException

Returns true if this real is smaller than r. Overridden to return false since the value is dynamic.

Specified by:

smaller in interface RAFullComparable

Overrides:

smaller in class RAReal

Parameters:

r - Another real bites the dust

Returns:

true or false, see above.

Throws:

RAException

largerEquals

public boolean largerEquals(RAFullComparable r)
                     throws RAException

Returns true if this real is larger than r or equals. Overridden to return false since the value is dynamic.

Specified by:

largerEquals in interface RAFullComparable

Overrides:

largerEquals in class RAReal

Parameters:

r - Another real bites the dust

Returns:

true or false, see above.

Throws:

RAException

smallerEquals

public boolean smallerEquals(RAFullComparable r)
                      throws RAException

Returns true if this real is smaller than r or equals r. Overridden to return false since the value is dynamic.

Specified by:

smallerEquals in interface RAFullComparable

Overrides:

smallerEquals in class RAReal

Parameters:

r - Another real bites the dust

Returns:

true or false, see above.

Throws:

RAException
