Data types

Half-precision floating point (f16)

A 16-bit floating point type; specifically, the ARM alternative half-precision. It is only available for aarch64 targets & it differs from it's IEEE variant by doing away with the special case for an exponent value of 31, disallawing infinities & NaNs. For non-compatible targets, the "f16" type is an alias of "f32"

See the Wikipedia article

Extended floating point (f80)

A 80-bit floating point type that provides greater precision than the basic floating-point formats. It is an x86 exclusive and it's mainly used to minimize roundoff and overflow errors in smaller floating point types. For non-compatible targets, the "f80" type is an alias of "f64"
