comparison include/core/bit_cast.h @ 369:47c9f8502269

Find changesets by keywords (author, files, the commit message), revision number or hash, or revset expression.
*: clang-format all the things I've edited the formatting a bit. Now pointer asterisks (and reference ampersands) are on the variable instead of the type, as well as having newlines for function braces (but nothing else)
