Please help me now!!
How about using this?
public int Add (int Number1) { return Number1 + 273.14; }
Just a basic.
i will try thank you
If You Want Something Like This 1(24)+273.15=
@SimpleFunction(description = "")
public int Add (int x) {
int b = 24;
return x*b + 273.14;
}
Or If You Want Just x+273.15=
@SimpleFunction(description = "")
public int Add (int x) {
return x + 273.14;
}

Try To change From Int To float

The error says that you are trying to return an double from a method that is defined to return an int, as this value is a double ( int value will store 273 only and you will lose 0.15) :
Therefore the addition operater will return a double. You can try to set your method return type to double.
