float32 Class Reference

A plain 32-bit float's bit pattern reinterpreted as a uint32_t, so instances can live in memory obtained from a capability-specific allocator (e.g. ESP32's MALLOC_CAP_32BIT, which some heap regions require for word-addressed access and won't necessarily hand out for a plain float array). Conversion to/from float is a zero-cost bitwise reinterpretation (see as_uint()/as_float()), not an encoding – unlike float16, this class is bit-for-bit identical to float and loses no precision or range; it exists purely to control storage/allocation, not to compress data.
