/* This include file defines several DPD and BCD conversion tables: */
/* */
/* uint16_t BCD2DPD[2458]; -- BCD -> DPD (0x999 => 2457) */
/* uint16_t BIN2DPD[1000]; -- Bin -> DPD (999 => 2457) */
/* uint8_t BIN2CHAR[4001]; -- Bin -> CHAR (999 => '\3' '9' '9' '9') */
/* uint8_t BIN2BCD8[4000]; -- Bin -> bytes (999 => 9 9 9 3) */
/* uint16_t DPD2BCD[1024]; -- DPD -> BCD (0x3FF => 0x999) */
/* uint16_t DPD2BIN[1024]; -- DPD -> BIN (0x3FF => 999) */
/* uint32_t DPD2BINK[1024]; -- DPD -> BIN * 1000 (0x3FF => 999000) */
/* uint32_t DPD2BINM[1024]; -- DPD -> BIN * 1E+6 (0x3FF => 999000000) */
/* uint8_t DPD2BCD8[4096]; -- DPD -> bytes (x3FF => 9 9 9 3) */
/* */
/* In all cases the result (10 bits or 12 bits, or binary) is right-aligned */
/* in the table entry. BIN2CHAR entries are a single byte length (0 for */
/* value 0) followed by three digit characters; a trailing terminator is */
/* included to allow 4-char moves always. BIN2BCD8 and DPD2BCD8 entries */
/* are similar with the three BCD8 digits followed by a one-byte length */
/* (again, length=0 for value 0). */
/* */
/* To use a table, its name, prefixed with DEC_, must be defined with a */
/* value of 1 before this header file is included. For example: */
/* #define DEC_BCD2DPD 1 */
/* This mechanism allows software to only include tables that are needed. */
