IsNaN

pub const fn IsNaN(Value: f16) -> bool

Classifies the exact f16 representation with IsNaN semantics. Value: Floating bits, including subnormals, signed zero and NaN payloads. Return: Classification without arithmetic, allocation or floating-status mutation.

IsFinite

pub const fn IsFinite(Value: f16) -> bool

Classifies the exact f16 representation with IsFinite semantics. Value: Floating bits, including subnormals, signed zero and NaN payloads. Return: Classification without arithmetic, allocation or floating-status mutation.

IsInfinity

pub const fn IsInfinity(Value: f16) -> bool

Classifies the exact f16 representation with IsInfinity semantics. Value: Floating bits, including subnormals, signed zero and NaN payloads. Return: Classification without arithmetic, allocation or floating-status mutation.

CopySign

pub const fn CopySign(Magnitude: f16, Sign: f16) -> f16

Returns f16 Magnitude bits with the sign bit of Sign. Magnitude: Bits whose exponent/fraction are preserved, including NaNs. Sign: Floating value supplying only its sign bit. Return: Exact bitwise sign replacement; no arithmetic or runtime dependency.
