Perform a floor operation on an input tensor.

Attention

Data type can be passed using the -DDATA_TYPE compile flag, e.g. -DDATA_TYPE=float

Vector size should be given as a preprocessor argument using -DVEC_SIZE=size. e.g. -DVEC_SIZE=16

Note

Can only take floating point data types.

Parameters

[in]	input_ptr	Pointer to the source image. Supported data types: F16/F32
[in]	input_stride_x	Stride of the source image in X dimension (in bytes)
[in]	input_step_x	input_stride_x * number of elements along X processed per workitem(in bytes)
[in]	input_stride_y	Stride of the source image in Y dimension (in bytes)

[in]	input_stride_z	Stride of the source tensor in Z dimension (in bytes)
[in]	input_step_z	input_stride_z * number of elements along Z processed per workitem(in bytes)
[in]	input_offset_first_element_in_bytes	The offset of the first element in the source image
[out]	output_ptr	Pointer to the destination image. Supported data types: same as input_ptr
[in]	output_stride_x	Stride of the destination image in X dimension (in bytes)
[in]	output_step_x	output_stride_x * number of elements along X processed per workitem(in bytes)
[in]	output_stride_y	Stride of the destination image in Y dimension (in bytes)
