计算简单的数学表达式;支持 int/float 和运算符:+ - * / % ^ ( ).
This class has a single generic static method Evaluate, that evaluates a mathematical expression and returns
the result.
Supported number types are: int
, float
, long
, double
.
The expressions that can be evaluated support:
arithmetic operators a+b
, a-b
, a*b
, a/b
,
power (a^b
) and modulo (a%b
) operators,
parentheses,
math functions sqrt(a)
, floor(a)
, ceil(a)
, round(a)
,
trigonometic functions cos(a)
, sin(a)
, tan(a)
(argument expressed in radians), and a constant pi
.
using UnityEditor; using UnityEngine;
public class ExampleScript : MonoBehaviour { [MenuItem("Example/Int Expression")] public static void IntExample() { ExpressionEvaluator.Evaluate("2+3", out int result); // prints 5 Debug.Log(result); }
[MenuItem("Example/Float Expression")] public static void FloatExample() { ExpressionEvaluator.Evaluate("sqrt(cos(pi/3))", out float result); // prints 0.7071068 Debug.Log(result); } }
Evaluate | Evaluates a math expression and returns the result. |
