5.1.11 INT_TO_REAL(_E)
Outline
This function converts word [signed] data into float (single precision) data, and outputs the data obtained by
conversion.

2. Set data
In explanation of functions, I/O variables inside ( ) are described.
Explanation of function and operation
This function converts word [signed] data stored in a device specified in into float (single precision) data,
and outputs the data obtained by conversion to a device specified in .
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.
3) The function is provided in the FX
3G Series Ver.1.10 or later.
