It would be easier to develop extensions and extension developers would not be
confused with strange errors.

And why not also support other types?
It would require a substantial amount of resources from the NetLogo team
in order to change this. On the other side of things, what substantial
advantage would it serve for NetLogo to be able to handle ints or longs?

long -> double.

NetLogo numbers must always be doubles, because much of the NetLogo
internals assumes as much. If that assumption isn't met, bad things
will happen. Fortunately, it's pretty easy to always just give NetLogo
doubles.

Hi, I' trying to pass number (int or long) from java etension as an argument to
task but have some issues with it. I tried both int and long and got two
different errors. When I cast the int/long into double then it works.
long:
```java
class Callbacks$Actuators{
public void attack(long id) {
attack.perform(ctx, new Object[] {id});
}
}
```
```
let tattack task [
let cislo int ?1
]
```
```
INT expected input to be a number but got the number <Long> instead.
error while zombie 85 running INT

int:
```java
class Callbacks$Actuators{
public void attack(int id) {
attack.perform(ctx, new Object[] {id});
}
}
```
```
