 * \brief C API: UFormattable is a thin wrapper for primitive types used for formatting and parsing.
 *
 * This is a C interface to the icu::Formattable class. Static functions on this class convert
 * to and from this interface (via reinterpret_cast).  Note that Formattables (and thus UFormattables)
 * are mutable, and many operations (even getters) may actually modify the internal state. For this
 * reason, UFormattables are not thread safe, and should not be shared between threads.
 *
 * See {@link unum_parseToUFormattable} for example code.
