Constructors

o EuReal 
 public EuReal(double t)
There is no way to alter the value of a EuReal

Parameters:
t - the value

Methods

o signOf 
 public static int signOf(double t)
Finds the sign of a passed double. All values in the range [-@see epsilon,@see epsilon] lead to the sign 0.

Returns:
-1, 0 or 1 depending on the sign of a double.
o toRadians 
 public static double toRadians(double a)
o toDegrees 
 public static double toDegrees(double a)
o compare 
 public int compare(double other)
Compares the value to another one, supplied either as a double or as another EuReal

Parameters:
other - the other value
Returns:
1 when this>other-epsilon, 0 when |this-other|other+epsilon
o compare 
 public int compare(EuReal other)
Parameters:
other - the other value
o identical 
 public boolean identical(double other)
Compares the value to another one, supplied as a double

Parameters:
other - the other value
Returns:
true if they are close up to @see epsilon
o identical 
 public boolean identical(EuReal other)
Compares the value to another one, supplied as another EuReal

Parameters:
other - the other value
Returns:
true if they are close up to @see epsilon
o val 
 public double val()
Returns:
the value as a double
o sign 
 public int sign()
Compares the value to zero

Returns:
1 when this>-epsilon, 0 when |this|epsilon
o toMouse 
 public int toMouse(mouseInfo info)
Parameters:
info - the @see mouseInfo cointaing scaling information
Returns:
the real scaled to pixels according to mouseInfo.
o properSuccession 
 public boolean properSuccession(double u,
                                 EuReal v)
Returns:
true if thisu>v param u another real value param v another real value
o succession 
 public boolean succession(double u,
                           EuReal v)
Returns:
true if this<=u<=v or if this=>u=>v param u another real value param v another real value
