The proper solution is to use std::bit_cast in modern C++ or otherwise use memcpy, and of course know what you're doing. Some things that could mess with you:

The proper solution is to use std::bit_cast in modern C++ or otherwise use memcpy, and of course know what you're doing. Some things that could mess with you: * Floating-point endianity is not the same as integer endianity. * Floating-point alignment requirements differ from integer alignment requirements. * The compuler is configured to use something else than 32-bit binary32 IEEE 754 for the type "float". * The computer does not use two's complement arithmetic for integers. In practice, these are not real problems.
