5.6.3 MINIMUM(_E)
Outline
This function searches the minimum value among data, and outputs the minimum value.
1. Format
*1. Output variable
2. Set data
In explanation of functions, I/O variables inside ( ) are described.
Explanation of function and operation
1) This function outputs the minimum value among ANY_SIMPLE type data stored in devices specified in
and to a device specified in using the data type of data stored in devices specified in
and .
Example: When the data type is word [signed]
2) The number of pins in can be changed.
Cautions
1) Use the function having "_E" in its name to connect a bus.
2) When handling 32-bit data in structured programs, you cannot specify 16-bit devices directly, different
from simple projects. Use labels when handling 32-bit data.
You can specify 32-bit counters directly, however, because they are 32-bit devices.
Use global labels when specifying labels.
