5.3.19 BCD Conversion (BCD)
( 1 ) Operation
The input data is converted from binary data to BCD data and stored in the output data.
If the input data is greater than 9,999, or a negative value, the result will be incorrect.
( 2 ) Format
∗ C and # registers cannot be used.
( 3 ) Programming Example
In the following programming example, the value 1,234 in input data A in MW00000 is converted to BCD and stored
in the output data in MW00001.
MW00000 = 1,234: (1
× 4,096) + (2 × 256) + (3 × 16) + 4 → MW00001 = 4,660 (1234 hex)
When performing operations with different data types, the result of the operation will depend on the data type of the output reg-
ister.
Refer to 4.4.2 ( 3 ) Precautions When Using Local Registers within a User Function for details.
Output data Input data
Converted to BCD.
The output data is computed as shown below when the input decimal data is abcd.
Output data = (a × 49) + (b × 256) + (c × 16) + d
