:nosearch: .. _op_ai_onnx_Sqrt-1: Sqrt - version 1 ================ This page documents version **1** of operator **Sqrt**. See :doc:`Sqrt` for the latest version (since version 13). - **Domain**: ``ai.onnx`` - **Since version**: 1 Square root takes one input data (Tensor ) and produces one output data (Tensor ) where the square root is, y = x^0.5, is applied to the tensor elementwise. If x is negative, then it will return NaN. **Inputs** - **X** (*T*): Input tensor **Outputs** - **Y** (*T*): Output tensor **Type Constraints** - **T**: Constrain input and output types to float tensors. Allowed types: tensor(double), tensor(float), tensor(float16).
