# Math::HALF_PI
|
||
|
||
```cpp
|
||
constexpr float HALF_PI = 1.57079632679489661923f;
|
||
```
|
||
|
||
`HALF_PI` 是圆周率除以 2，即 90 度对应的弧度值，约为 1.57079632679489661923。该常量常用于角度与弧度的转换、四分之一圆周计算等场景。
|
||
|
||
**示例：**
|
||
|
||
```cpp
|
||
#include <XCEngine/Core/Math/Math.h>
|
||
|
||
float ninetyDegreesRadians = HALF_PI;
|
||
```
