I found these snippets:
https://psalm.dev/r/d80a43c7d8
<?php
/**
* @template T of int|null
* @param T $a
* @return (T is null ? null : int)
*/
function add(?int $a, int $b):?int {
if ($a === null){
return null;
}
return $a + $b;
}Psalm output (using commit 16b24bd):
ERROR: InvalidReturnStatement - 12:12 - The inferred type 'float|int' does not match the declared return type 'int|null' for add
ERROR: InvalidReturnType - 6:12 - The declared return type 'int|null' for add is incorrect, got 'float|int|null'

If the result of the addition is larger than PHP_INT_MAX php will convert it to a float.

@M393 makes sense, thank you!
But why Psalm is not reporting anything in case of addition of two not nullable integers?
