 * SUMMARY: Testing the |acos()| method for the Math object.  The acos method 
 * returns a numeric value between 0 and pi radians. If the value of number is
 * outside this range, it returns NaN. Because acos is a static method of Math,
 * you always use it as Math.acos(), rather than as a method of a Math object
 * you created. 
 *
 * Syntax:  |acos(x)|  where x is a number.
