+/** This is a structure containing members pertaining to the formatting and display of numeric values.\r
+ Each member of this structure is commented with its value in the "C" locale.\r
+\r
+ The decimal_point member must point to a string with a length greater than zero.\r
+ All other pointer members may point to "" in order to indicate that the value is not available\r
+ in the current locale, or that it is of zero length. Except for grouping and mon_grouping, the\r
+ strings start and end in the initial shift state.\r
+\r
+ The remaining members, of type char, are non-negative numbers or CHAR_MAX, which indicates that\r
+ the value is not available in the current locale.\r
+\r
+ Members grouping and mon_grouping point to strings where each element (character) of the string\r
+ indicates the size of the corresponding group of digits and is interpreted as follows:\r
+ - CHAR_MAX No further grouping is to be performed.\r
+ - 0 The previous element is to be repeatedly used for the remainder of the digits.\r
+ - other The ISO specification states: "The integer value is the number of digits that\r
+ compose the current group. The next element is examined to determine the size\r
+ of the next group of digits before the current group." The EDK II implementation\r
+ interprets this to mean that the groups are specified left-to-right.\r
+\r
+ The *_sep_by_space members are interpreted as follows:\r
+ - 0 No space separates the currency symbol and value.\r
+ - 1 If the currency symbol and sign string are adjacent, a space separates them from the\r
+ value; otherwise, a space separates the currency symbol from the value.\r
+ - 2 If the currency symbol and sign string are adjacent, a space separates them;\r
+ otherwise, a space separates the sign string from the value.\r
+ For int_p_sep_by_space and int_n_sep_by_space, the fourth character of int_curr_symbol is\r
+ used instead of a space.\r
+\r
+ The values of the *_sign_posn members are interpreted as follows:\r
+ - 0 Parentheses surround the quantity and currency symbol.\r
+ - 1 The sign string precedes the quantity and currency symbol.\r
+ - 2 The sign string succeeds the quantity and currency symbol.\r
+ - 3 The sign string immediately precedes the currency symbol.\r
+ - 4 The sign string immediately succeeds the currency symbol.\r
