# MyStack.Formula
公式运算
## 调用方式
```
// 服务注入
var services = new ServiceCollection();
services.AddFormula(context.Configuration, configure =>
{
// 配置JSON数据源
configure.UseConfigurationIdValue();
});
```
## 功能
```
// 调用
var formulaEngine = serviceProvider.GetRequiredService();
```
### 运算符 `+`、`-`、`*`、`/`、`^`
```
// 结果：2
var actualValue = formulaEngine.Calculate("1+1");
```
### 括号符
```
// 结果：4
var actualValue = formulaEngine.Calculate("(1+1)*2");
```
### 复杂公式
```
// 调用
// 结果：9.001953125
var actualValue = formulaEngine.Calculate("3+4*2/(1-5)^2^3+2*(2+1)");
```
### 三角函数
```
// 调用
// 结果：1024
var actualValue = formulaEngine.Calculate("COS(900-3*10*30)+123.45+30*30-0.45+TAN(0)");
```
### 数据源
#### 值类型计算
```
// 配置Id的值为：<1> = 1
// 结果：4
var actualValue = formulaEngine.Calculate("(1+<1>)*2");
```
#### 公式类型计算
```
// 配置Id的值为：<2> = (2+1)*2
// 结果：22
var actualValue = formulaEngine.Calculate("(1+<1>)*2");
```
