To support compatibility with older readers, implementations of parquet-format
should
write `DecimalType` precision and scale into the corresponding SchemaElement
field in metadata.
+### Half-precision floating-point
+
+Also known as `float16`. Used in contexts where precision is traded off for
performance and efficient storage.
Review Comment:
```suggestion
### FLOAT16
The `FLOAT16` annotation represents half-precision floating-point numbers
in the 2-byte IEEE little-endian format.
Used in contexts where precision is traded off for smaller footprint and
potentially better performance.
