Function
Converts the specified float value to 4-byte data. The byte order is in DCBA order.
Format
modbus_set_float_dcba( value , dest )
Parameters
value[ VB.NET： Single ] [ C, C++： float ] [ C#： float ] [ Python： ctypes.c_float ]
Specify the conversion data.
dest[ VB.NET： UShort ] [ C, C++： uint16_t * ] [ C#： ushort[] ] [ Python： ctypes.POINTER(ctypes.c_uint16) ]
Specify the pointer of the array that stores the float conversion result.
The premise is that the number of elements in the array is two, and each contains 16-bit data.
Return values
None
Remarks
Converts the specified float value to 4-byte data. The byte order is in DCBA order.
The premise is that the dest array has two elements and each has a 16-bit value.
Example
Gets 4-byte data from the float value.
