Neonfloat32x4_tvmaxnmq_f32(float32x4_t a, float32x4_t b)Vector arithmetic / Minimum
Description
Floating-point Maximum Number (vector). This instruction compares corresponding vector elements in the two source SIMD&FP registers, writes the larger of the two floating-point values into a vector, and writes the vector to the destination SIMD&FP register.
