"epsilon" is only recognized by the CAS. It cannot be used in Home or in non-CAS programs or functions.

That's right...
It crashes the calculator on Android...

Code:



 EXPORT Z_SGN(XX)
 BEGIN
  RETURN ((XX>0)-(XX<0));
 END;
 

EXPORT SG()
BEGIN
 {Z_SGN(0.01),Z_SGN(0),Z_SGN(−0.01)};
 Z_SGN(approx(CAS.epsilon)); // CRASHES ON ANDROID 
END;
