Function
Converts the specified float value to 4-byte data. The byte order is in CDAB order.
Format
modbus_set_float_cdab( value , dest )
Parameters
value [ C : float ] [ Python : ctypes.c_float ]
Specify the conversion data.
dest [ C : uint16_t * ] [ 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 CDAB 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.
