TensorFlow：useful operators

---

• tf.add(x, y) Add two tensors of the same type, x + y
• tf.subtract(x, y) Subtract tensors of the same type, x - y
• tf.multiply(x, y) Multiply two tensors element-wise
• tf.pow(x, y) Take the element-wise power of x to y
• tf.exp(x) Equivalent to pow(e, x), where e is Euler’s number (2.718…)
• tf.sqrt(x) Equivalent to pow(x, 0.5)
• tf.div(x, y) Take the element-wise division of x and y
• tf.truediv(x, y) Same as tf.div, except casts the arguments as a float
• tf.floordiv(x, y) Same as truediv, except rounds down the final answer into an integer
• tf.mod(x, y) Takes the element-wise remainder from division
