in B4X (not sure about B4R), B4x casts types automatically as needed. It also converts numbers to strings and vice versa automatically.
This is convenient but can also be dangerous due to loss of data.
In Java, those conversions that may lose data are called narrowing and must be explicitly demanded by the programmer using a cast
Would it be possible to implement that the IDE issues a warning when narrowing takes place?

B4X:
Private i As Int = 50000
Private s As Short = 0
s = i
Log(s) '-15536In Java, those conversions that may lose data are called narrowing and must be explicitly demanded by the programmer using a cast
B4X:
int i = 50000;
short s = 0;
//s = i; //error when writing code
s = (short) i; //explicit casting
System.out.println(s); //-15536Would it be possible to implement that the IDE issues a warning when narrowing takes place?
