# Divide¶

Versioned name: Divide-1

Category: Arithmetic binary

Short description: Divide performs element-wise division operation with two given tensors applying broadcasting rule specified in the auto_broadcast attribute.

Detailed description Before performing arithmetic operation, input tensors a and b are broadcasted if their shapes are different and auto_broadcast attribute is not none. Broadcasting is performed according to auto_broadcast value. After broadcasting Divide performs division operation for the input tensors a and b using the formula below:

$o_{i} = \frac{a_{i}}{b_{i}}$

The result of division by zero is undefined.

Attributes:

• m_pythondiv

• Description: specifies if floor division should be calculate. This attribute is supported only for integer data types.

• Range of values:

• false - regular division

• true - floor division

• Type: boolean

• Default value: true

• Required: no

• Description: specifies rules used for auto-broadcasting of input tensors.

• Range of values:

• Type: string

• Default value: “numpy”

• Required: no

Inputs

• 1: A tensor of type T and arbitrary shape and rank. Required.

• 2: A tensor of type T and arbitrary shape and rank. Required.

Outputs

• 1: The result of element-wise division operation. A tensor of type T with shape equal to broadcasted shape of the two inputs.

Types

• T: any numeric type.
