# Non-Boolean values

Truth of Non-Boolean values

FlowScript is fairly permissive when it comes to evaluating the truth of non-Boolean values. The following non-Boolean values count as true:

* All numbers except 0
* All strings except the empty string, `"0"` and `"FALSE"` (including all upper- and lowercase variants)
