Div - version 7#

This page documents version 7 of operator Div. See Div for the latest version (since version 14).

  • Domain: ai.onnx

  • Since version: 7

Performs element-wise binary division (with Numpy-style broadcasting support).

This operator supports multidirectional (i.e., Numpy-style) broadcasting; for more details please check the broadcasting behavior in ONNX.

For integer inputs, the result is computed using truncating division (rounding toward zero).

Inputs

  • A (T): First operand.

  • B (T): Second operand.

Outputs

  • C (T): Result, has same element type as two inputs

Type Constraints

  • T: Constrain input and output types to high-precision numeric tensors. Allowed types: tensor(double), tensor(float), tensor(float16), tensor(int32), tensor(int64), tensor(uint32), tensor(uint64).

-If necessary the right-hand-side argument will be broadcasted to match the

-tensor with rank equal to or smaller than the first tensor), or having its

+Performs element-wise binary division (with Numpy-style broadcasting support).

-For example, the following tensor shapes are supported (with broadcast=1):
-
-  shape(A) = (2, 3, 4, 5), shape(B) = (,), i.e. B is a scalar tensor
-  shape(A) = (2, 3, 4, 5), shape(B) = (1, 1), i.e. B is an 1-element tensor
-  shape(A) = (2, 3, 4, 5), shape(B) = (5,)
-  shape(A) = (2, 3, 4, 5), shape(B) = (4, 5)
-  shape(A) = (2, 3, 4, 5), shape(B) = (3, 4), with axis=1
-  shape(A) = (2, 3, 4, 5), shape(B) = (2), with axis=0

-Attribute `broadcast=1` needs to be passed to enable broadcasting.
