  53.      _e_p is the general name for the set of intrinsic functions which return
  54.      the numeric characteristics of each of the standard numeric types.
  55.  
  56.      _e_p_b_a_s_e - returns the base for the type of the argument (for floating
  57.      point types, _e_p_b_a_s_e returns the base of the mantissa).  Currently this is

  74.      _e_p_p_r_e_c - returns the precision (in terms of power of the base) for the
  75.      type of the argument.  The sign bit (if any) is not included in the
  76.      precision.  The assumed bit (see IEEE floating point specifications), if
  77.      any, will be included in the precision.
  78.  
  79.      _e_p_e_m_i_n, _e_p_e_m_a_x - returns the minimum (or maximum) exponent for the
  80.      floating point type of the argument.
  81.  
  82.      _e_p_t_i_n_y, _e_p_h_u_g_e - returns the smallest (or largest) non-zero positive
  83.      number in the type of the argument.
  84.  
  85.      _e_p_m_r_s_p - returns the epsilon for the floating point type of the argument.
