_D_e_s_c_r_i_p_t_i_o_n:

     Get details of the numerical representations in the current
     locale.

_U_s_a_g_e:

     Sys.localeconv()

_V_a_l_u_e:

     A character vector with 18 named components. See your ISO C
     documentation for details of the meaning.

     It is possible to compile R without support for locales, in which
     case the value will be `NULL'.

_S_e_e _A_l_s_o:

     `locales' for ways to set locales: by default R uses the C clocal
     for `"LC_NUMERIC"' and `"LC_MONETARY"'.
