         Musimat includes standard mathematical functions such as Sqrt(x). There are trigono-
         metric functions such as Sin(x), Cos(x), and Tan(x). Arguments to trigonometric functions 
         are in real radian values. Speaking of radian measure, here's an interesting way to compute Pi to 
         the machine precision of your computer:
         *****************************************************************************/
        
        Const Real Pi = Atan(1.0) * 4.0;                        // arctangent of 1 times 4 equals Pi
        Print("Pi=", Pi);
        
        /*****************************************************************************
         The function Abs(x) returns the absolute value of its argument. It works for either Real or 
         Integer expressions. For instance, both of the following statements will print True:
         *****************************************************************************/
        
        If (Abs(-5) == Abs(5))  // Integer Abs( )
                Print(True); 
        Else 
                Print(False);
        
        If (Abs(-5.0) == Abs(5.0)) // Real Abs( ) 
                Print(True); 
        Else 
                Print(False);
        
        /*****************************************************************************
         With no arguments, the built-in function Random() returns a real random value between 0.0 and 
         1.0, but if Random() is given arguments specifying Real lower and upper bounds, it returns a 
         Real random value between those boundaries. For example,
         *****************************************************************************/
        
        Real x = Random(0.0, 11.0);
        Print(x);
        
        /*****************************************************************************
         returns a random Real value in the range 0.0 <= x < 11.0. Note the range is from 0.0 to almost 11.0.
         
         If Random() is given arguments specifying Integer lower and upper bounds, it returns an 
         Integer random value between those boundaries. For example,
         *****************************************************************************/
        
        Integer y = Random(0, 11);
        Print(y);
        
        /*****************************************************************************
         returns a random Integer value in the range [0..11]. Note the range is inclusive from 0 to 11.
         *****************************************************************************/
