# usesFloatComponents

A Boolean value that indicates whether vector components are floating-point values.

```
var usesFloatComponents: Bool { get }
```

## Discussion

If <doc://com.apple.documentation/documentation/Swift/true>, SceneKit interprets the geometry source’s data as an array of vectors whose components are floating-point values. The type of floating-point value is determined by the [`SCNGeometrySource`](/documentation/SceneKit/SCNGeometrySource) property: 4 bytes for `float` values or 8 bytes for `double` values.

If <doc://com.apple.documentation/documentation/Swift/false>, SceneKit interprets the geometry source’s data as an array of vectors whose components are integer values. The type of integer value is determined by the [`SCNGeometrySource`](/documentation/SceneKit/SCNGeometrySource) property; for example, 2 bytes for `unsigned short` values or 4 bytes for `unsigned int` values.
