-Data truncation will occur when the values in the range exceed the range of the specified output data type e.g. when a float value is assigned to an {{MLOperandDataType/"int8"}} data type, etc.

-    **Arguments:**
-        - *start*: a {{float}} scalar. The starting value of the range.
-        - *end*: a {{float}} scalar. The ending value of the range.
-        - *step*: a {{float}} scalar. The gap value between two data points in the range.
-        - *type*: an optional {{MLOperandDataType}}. If not specified, it is assumed to be {{MLOperandDataType/"float32"}}.
-    **Returns:** an {{MLOperand}}. The constant 1-D output tensor of size `max(0, ceil((end - start)/step))`.
