#### {{MLGraphBuilder/constant(start, end, step, type)}} #### {#api-mlgraphbuilder-constant-range}
Create a constant {{MLOperand}} of the specified data type and shape that contains the data as specified by the range.

<div class="note">
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.
</div>

<div>
**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))`.
</div>

<summary>
The <dfn method for=MLGraphBuilder>constant(|start|, |end|, |step|, |type|)</dfn> method steps are:
</summary>
1. Let |descriptor| be a new {{MLOperandDescriptor}}.
1. Set |descriptor|.{{MLOperandDescriptor/dataType}} to |type|.
1. Let |size| be max(0, ceil((|end| - |start|)/|step|)).
1. If |size| is not a [=valid dimension=], then [=exception/throw=] a {{TypeError}}.
1. Set |descriptor|.{{MLOperandDescriptor/dimensions}} to the [=/list=] « |size| ».
1. *Make graph connections:*
1. Let |operand| be the result of [=creating an MLOperand=] given [=this=] and |descriptor|.
1. Let |buffer| be an [=implementation-defined=] platform memory buffer the size of |size| multiplied by sizeof(|descriptor|.{{MLOperandDescriptor/dataType}}).
1. [=list/For each=] |index| in [=the range=] 0 to |size|, exclusive:
1. Set |buffer|[|index|] to |start| + (|index| * |step|).
1. Add |operand| to [=this=]'s [=MLGraphBuilder/graph=]'s [=computational graph/constants=] with |buffer| as value.
1. Return |operand|.
