_D_e_s_c_r_i_p_t_i_o_n_:

     These functions compute miscellaneous mathematical
     functions.  The naming follows the standard for com-
     puter languages such as C or Fortran.

_U_s_a_g_e_:

     abs(x)
     sqrt(x)

_S_e_e _A_l_s_o_:

     `Arithmetic' for simple, `log' for logarithmic, `sin'
     for trigonometric, and `Special' for special mathemati-
     cal functions.

     xx <- -9:9
     plot(xx, sqrt(abs(xx)),  col = "red")
     lines(spline(xx, sqrt(abs(xx)), n=101), col = "pink")
