Binary conversion

Expression

Input

[ A BIN B ]

Output

Function

When the input is ON, this instruction converts the 4 digits of BCD data of A into binary, and stores
in B. If any digit of A contains non-BCD code (other than H0 through H9), the conversion is not
executed and the instruction error flag (ERF = S051) is set to ON.

Example

When R017 is ON, the BCD data of RW28 is converted into binary data, and the result is
stored in D0127.
For example, if RW28 is H1234, the binary data 1234 is stored in D0127.

Note

If any digit of operand A contains non-BCD data, e.g. H13A6, the conversion is not executed

and the instruction error flag (ERF = S051) is set to ON.
