The code below produces a float, although it seems to produce an integer.

This is due to (int) having higher precedence than multiplication: it is applied to $c, without effect.

@dseguy same for ternary operator. That's why explicit things like ( ) is recommended to avoid problems 😅

@velkuns Yes, I can do a long list of those operators... Fun with precedence!

@dseguy This is why I think cast operators should not have a space after them.

echo (int)$c * 0.12345;

@zimzat It does make it more readable.

@dseguy yep, if you wanted an integer, you'd wrap the expression in parenthesis before casting.

$myInt = (int) ($c * 0.12345);

Casting applies to the thing directly after it.
