# RectInt::GetBottom
```cpp
int32_t GetBottom() const;
int32_t GetBottom() const
```
获取矩形下边界 y 坐标
获取矩形下边界。
**返回:** 矩形下边界 y 坐标(等于 y + height
**线程安全:**
**返回:** `int32_t` - 下边界坐标 (y + height)
**复杂度:** O(1)
**示例:**
```cpp
#include "XCEngine/Math/Rect.h"
#include <iostream>
using namespace XCEngine::Math;
int main() {
RectInt rect(10, 20, 100, 50);
int32_t bottom = rect.GetBottom();
std::cout << "Bottom: " << bottom << "\n";
return 0;
}
RectInt rect(10, 20, 100, 50);
int32_t bottom = rect.GetBottom(); // 70
```
