Package float16 implements the 16-bit floating point data type (IEEE 754-2008). This implementation provides conversion between float16 and other floating-point types (float32 and float64) with support for various rounding modes and error handling. The float16 type supports all IEEE 754-2008 special values: When converting to higher-precision types (float32/float64), subnormal float16 values are preserved. However, when converting back from higher-precision types to float16, subnormal values may be rounded to the nearest representable normal float16 value. This behavior is consistent with many hardware implementations that handle subnormals in a similar way for performance reasons. The following rounding modes are supported for conversions: Conversion functions with a ConversionMode parameter can return errors for: See: http://en.wikipedia.org/wiki/Half-precision_floating-point_format
