Hello  
Is there any quick way to verify if a passed number is integer or not ? I’d love something like Isinteger() but it doesnt exist, so I was wondering if you know any workarounds, thanks

Assuming you have a Variant and you want to know if it is an Integer or Double:

`If var.Type = Variant.TypeDouble Then
  ...`

Nice, Eli! Am i right when i say that if it’s not a Variant, Horacio could assign the Value to a Variant and then perform the above Test?

Thanks I found an alternative way:  
If a number X is sumultanoisly both ceil and floor then it must be integer.

I hope there are not exceptions. So far it works

Thanks anyways

Yes (note that this is different AFAIK as with Auto).

That will tell you if it contains an Integer VALUE, but NOT if the variable TYPE is integer

and you don’t need to check BOTH…

```auto
If X=floor(x) then its an integer value
if X=ceil(x) then its an integer value
```
