    let a = F16::from_bits(a);
    let b = F16::from_bits(b);
    let d = a.add(b, RoundingMode::TiesToEven);

    let a = f32::from_bits(a.to_f32(RoundingMode::TiesToEven).bits());
    let b = f32::from_bits(b.to_f32(RoundingMode::TiesToEven).bits());
    let d = f32::from_bits(d.to_f32(RoundingMode::TiesToEven).bits());
