# SDL_GetRectAndLineIntersectionFloat
Calculate the intersection of a rectangle and line segment with float precision.
## Header File
Defined in [](https://github.com/libsdl-org/SDL/blob/main/include/SDL3/SDL_rect.h)
## Syntax
```c
bool SDL_GetRectAndLineIntersectionFloat(const SDL_FRect *rect, float *X1, float *Y1, float *X2, float *Y2);
```
## Function Parameters
| | | |
| ------------------------------ | -------- | ---------------------------------------------------------------------------- |
| const [SDL_FRect](SDL_FRect) * | **rect** | an [SDL_FRect](SDL_FRect) structure representing the rectangle to intersect. |
| float * | **X1** | a pointer to the starting X-coordinate of the line. |
| float * | **Y1** | a pointer to the starting Y-coordinate of the line. |
| float * | **X2** | a pointer to the ending X-coordinate of the line. |
| float * | **Y2** | a pointer to the ending Y-coordinate of the line. |
## Return Value
(bool) Returns true if there is an intersection, false otherwise.
## Remarks
This function is used to clip a line segment to a rectangle. A line segment
contained entirely within the rectangle or that does not intersect will
remain unchanged. A line segment that crosses the rectangle at either or
both ends will be clipped to the boundary of the rectangle and the new
coordinates saved in `X1`, `Y1`, `X2`, and/or `Y2` as necessary.
## Version
This function is available since SDL 3.0.0.
