A set of intrinsics is provided to perform this type of conversion. Syntax vreinterpret{q}_dsttype_srctype Where: q dsttype srctype Specifies that the conversion operates on 128-bit vectors. If it is not present, the conversion operates on 64-bit vectors. Represents the type to convert to. Represents the type being converted. Example The following intrinsic reinterprets a vector of four signed 16-bit integers as a vector of four unsigned integers: uint16x4_t vreinterpret_u16_s16(int16x4_t a); The following intrinsic reinterprets a vector of four 32-bit floating point values integers as a vector of four signed integers. int8x16_t vreinterpretq_s8_f32(float32x4_t a); These conversions do not change the bit pattern represented by the vector.
