Function NameDescription
SINT_TO_BCD_BYTEConvert a small integer (SINT) to two BCD digits encoded in a BYTE.
INT_TO_BCD_WORDConvert an integer (INT) to four BCD digits encoded in a WORD.
DINT_TO_BCD_DWORDConvert a double integer (DINT) to eight BCD digits encoded in a DWORD.
LINT_TO_BCD_LWORDConvert a long integer (LINT) to sixteen BCD digits encoded in a LWORD.

Examples

The function call SINT_TO_BCD_BYTE( 69 ) returns 16#69.
In this example the bit pattern 0100 0101 is converted to 0110 1001.
