        Numerical parameters can be given in the command line for tests.
        Three least significant bits of the first parameter:
        LSB: verbose.
        LSB+1: run a test for Int().
        LSB+2: run a test for Float().
        If exactly 2 parameters are given, the second is the length of a 
        randomly generated test sequence.
        If more than 2 parameters are given, the second and further parameters
        are used as the test sequence (two times if both tests are run).
        No parameters is equivalent to giving two pamaters 6 32 (i.e. both two
        tests not verbose with sequences of 32 random numbers each).
