.. index:: pair: page; TypeCast .. _doxid-dev_guide_op_typecast: TypeCast ======== General ~~~~~~~ TypeCast operation performs element-wise cast from input data type to the data type given by output tensor. It requires that :math:`\src` and :math:`\dst` have the same shape and layout. Rounding to nearest even will be used during cast. Operation attributes ~~~~~~~~~~~~~~~~~~~~ TypeCast operation does not support any attribute. Execution arguments ~~~~~~~~~~~~~~~~~~~ The inputs and outputs must be provided according to below index order when constructing an operation. Inputs ------ ====== ============== ===================== Index Argument Name Required or Optional ====== ============== ===================== 0 ``src`` Required ====== ============== ===================== Outputs ------- ====== ============== ===================== Index Argument Name Required or Optional ====== ============== ===================== 0 ``dst`` Required ====== ============== ===================== Supported data types ~~~~~~~~~~~~~~~~~~~~ TypeCast operation supports the following data type combinations. ========== ========== Src Dst ========== ========== bf16, f16 f32 f32 bf16, f16 ========== ========== .. note:: This operation is to support :ref:`mixed precision ` computation.
