# `GSRadialGradient.endRadius`

*Instance Property*

The radius of the end circle, relative to the drawing bounds.

## Declaration

```swift
var endRadius: CGFloat { get set }
```

```objc
@property (nonatomic) CGFloat endRadius;
```

```python
endRadius() -> float
setEndRadius_(endRadius: float)
```

## Discussion

The value is relative to the bounding rectangle in which the gradient drawn. To get the absolute value, multiple the stored value by the square root of the product of the side lengths of the bounding rectangle.
