Double vs Int

[victorlam]

Hello,

Please help to advise on the clarification between int and double especially using formula

For example

public int Myfunc()
xxxx

public double Myfunc()
xxx

Can anyone share the difference when the formula is set?
According to my understanding, int refers to the integer number 1, 2, … and double means the floating number. Do you need to click the correct type within Administrator? If the original value is integer, then I have a calculation of divided by 10 and become 1.5. How can we handle this? Or it still consider as int.

Hello,

The default data type for channels is double. This data type allows to store either integers or floats. Channel formulas should return double because channels are stored as doubles.
I recommend, not to use channel data type in the Channels table if you don’t have significant reasons to do that. Channel data type must match a tag data type provided by a device driver, which is double in most cases.
