The sign value of a field.

## Constructors

- [SignField](https://developer.rhino3d.com/api/gh2/type/grasshopper2.types.fields.standard.signfield/ctor.md): (2 overloads) Create a new absolute field.

## Properties

- [Name](https://developer.rhino3d.com/api/gh2/type/grasshopper2.types.fields.standard.signfield/name.md)
- [Type](https://developer.rhino3d.com/api/gh2/type/grasshopper2.types.fields.standard.signfield/type.md)

## Methods

- [ScalarAt](https://developer.rhino3d.com/api/gh2/type/grasshopper2.types.fields.standard.signfield/scalarat.md): Evaluate the field scalar component at a specific point in space. If this is a vector-field, the returned value is *probably* the magnitude of the vector, but this is not guaranteed.
- [VectorAt](https://developer.rhino3d.com/api/gh2/type/grasshopper2.types.fields.standard.signfield/vectorat.md): Evaluate the field vector component at a specific point in space. If this is a scalar-field, the returned value is *probably* a vector in the form (0,0,scalar), but this is not guaranteed.
