CONFIG_FP16

Half-precision floating point support

Type: bool

Help

This option enables the half-precision (16-bit) floating point support
via the `__fp16` (both IEEE and ARM alternative formats) and the
`_Float16` (IEEE format only) types.

Direct dependencies

ARM

(Includes any dependencies from ifs and menus.)

Default

y
