@typeswitch Actual comment from a C library I'm working on.

I'm not a C programmer usually, but it seems I've fallen into the same trap.

EDIT: Alt-text

A comment from a C library that says:

(Almost) Everything from here on will be composed with the raw float memory We use a uin32_t to represent the raw float data because it is a container of the same size. It also supports all the operations we want to do from here on.

C/C++ implicit conversion will turn it into a value-preserving integer, but not a data-preserving integer. For instance, the implicit conversion of 12.5 to an integer will become 13, which preserves value (as much as possible), but the memory layout will be entirely different.

All explicit conversions to raw memory then to another type are to leave memory layout completely unaltered, which allows us to do our magic.
