2.1.72. `--fp16_format=format`

This option enables the use of half-precision floating-point numbers as an optional extension to the VFPv3 architecture. If a format is not specified, use of the __fp16 data type is faulted by the compiler.

Syntax

--fp16_format=format

Where format is one of:

alternative: An alternative to ieee that provides additional range, but has no NaN or inifinity values.
ieee: Half-precision binary floating-point format defined by IEEE 754r, a revision to the IEEE 754 standard.
none: This is the default setting. It is equivalent to not specifying a format and means that the compiler faults use of the __fp16 data type.
