	// it provides an implementation of ReLU without branching.
	// the core idea of branchless-ReLU is the following.
	// 1. first, bitwise-and with 0 bits everytime returns 0 bits. but bitwise-and
	// with 1 bits returns the original argument kept intact.
	// 0000 & 1010 == 0000, 1111 & 1010 == 1010
	// 2. second, we can make 0 bits or 1 bits depending on the sign bit by applying
	// right arithmetic shift 31 times.
	// 1000 >> 31 == 1111, 0110 >> 31 == 0000
