WebDec 28, 2024 · In auto aa = { range };, the use of auto has its own rules of type deduction, and the rule is that this syntax (without * or [] in the declarator) deduces aa as having type std::initializer_list of one element.. Note that it would still not be correct to say that { range } has a type. The std::initializer_list is initialized by the elements of the braced list. WebBasically you are trying to cast an array of four 8-bit values which can have any alignment they like (byte alignment) to a 32-bit float value which needs 4-byte alignment. And the two just don't mesh. Instead you need to work the other way around - cast a type that has smaller alignment requirements over the type that has larger requirements. gym ascot
