Two schools

There are two schools how to write numerical code, which in this document we will call the IEEE school and the Fortran school.

One end of the spectrum: no changes in floating point by the compiler, the developer must express exact intent. This is the IEEE school.

On the other end of the spectrum: Developer specifies math, the compiler is

/* Allocate aligned memory in a portable way.
 *
 * Memory allocated with aligned alloc *MUST* be freed using aligned_free.
 *
 * @param alignment The number of bytes to which memory must be aligned. This
 *  value *must* be <= 255.
 * @param bytes The number of bytes to allocate.
 * @param zero If true, the returned memory will be zeroed. If false, the
 *  contents of the returned memory are undefined.
 * @returns A pointer to `size` bytes of memory, aligned to an `alignment`-byte
