## No true branch when evaluating an if expression in Erlang
|
||
|
|
|
||
|
|
Reports an error when none of the branches of an `if` expression evaluate to true. Corresponds to the `if_clause` error in the Erlang runtime.
|
||
|
|
|
||
|
|
For example, if we call `sign(0)` and the full definition of `sign` is
|
||
|
|
```erlang
|
||
|
|
sign(X) ->
|
||
|
|
if
|
||
|
|
X > 0 -> positive;
|
||
|
|
X < 0 -> negative
|
||
|
|
end.
|
||
|
|
```
