## 数字计算
在GameMaker Studio 2中包含了大量的函数用以处理不同的数学问题，其中包含各种类型的数字和日期、时间等等。大多数功能都可以做以下几处找到：
[Date and Time](DateandTime.md)
[Number Functions](RealValuedfunction.md)
[Vector Functions](VectorFunctions.md)
Matrix Functions
另外还有一些内置的常量，可被用来作为实数进行判断校验（不过你应该去校验常量而不是这些具体的值）
| 常量 | 值 |
| --- | --- |
| true | 1 |
| false | 0(其实只要小于1的值都会被判断为假) |
|pi|3.141592653589793280etc... (具体的值取决于不同平台的定义)|
