  Scalar, Input, Output, Interpolation Enum, Extrapolation Enum
</h2>

Use piece-wise interpolation to compute the output value of a function approximated by a set of field data points.

### Inputs

| Name | Type | Description |
| - | - | - |
| Value | [Scalar](../../../../block-documentation/types/scalar) | The value to look up in from the input domain. |
| Input | [Scalar List](../../../../block-documentation/types/scalar) | The input data for the function (must be monotonic). |
| Output | [Scalar List](../../../../block-documentation/types/scalar) | The output field data for the function (must be the same length as the input data). |
| Interpolation | Interpolation Enum | Interpolation type. |
| Extrapolation | Extrapolation Enum | How to extend data outside of the input domain. |

### Outputs

| Type |
| - |
| [Scalar](../../../../block-documentation/types/scalar) |
