Neonfloat64x2_tvsqrtq_f64(float64x2_t a)Vector arithmetic / Square root
Description
Floating-point Square Root (vector). This instruction calculates the square root for each vector element in the source SIMD&FP register, places the result in a vector, and writes the vector to the destination SIMD&FP register.
