Sqrt¶
Versioned name : Sqrt-1
Category : Arithmetic unary
Short description : Square root element-wise operation.
Detailed description : Sqrt performs element-wise square root operation on a given input tensor a, as in the following mathematical formula, where o is the output tensor:
\[o_{i} = \sqrt{a_{i}}\]
If the input value is negative, then the result is undefined.
For integer element type the result is rounded (half up) to the nearest integer value.
Attributes : Sqrt operation has no attributes.
Inputs
1 : A tensor of type T and arbitrary shape. Required.
Outputs
1 : The result of element-wise Sqrt operation. A tensor of type T and the same shape as input tensor.
Types
T : any numeric type.
