Steps to reproduce
When using the PowerToys Run calculator (triggered by =), the constant e (Euler's number) sometimes gets stuck as e - 1 (≈0.71828) instead of the correct value ≈2.71828.
In some cases, after further misuse, it can even become a random negative number like -169.28.
This appears to be a caching bug: the internal variable e is mistakenly overwritten with e - 1( sometime is e - 2 , even other value)) and persists across calculations.
在 PowerToys Run 计算器（输入 = 触发）中，数学常数 e 有时会错误地变成 e - 1（约 0.71828）而不是正确的 2.71828。
某些错误操作后，甚至会变成负值（如 -169.28）。
这看起来是一个缓存 bug：内部变量 e 被错误覆盖为 e - 1(有时为e-2甚至其他更加错误的值)，并且会“粘住”(除非退出，否则e的值永久变更)。
Steps to Reproduce / 重现步骤
Open PowerToys Run (L Alt+Space)
Type = to enter calculator mode
Enter a complex expression with e and multiple unary minus signs, for example:
this: (-(--334e-12) / (900e---1))
Now type "e" and check the value of "e"
May it will actual output: 0.7182818285 (incorrect, should be 2.71828…)
打开 PowerToys Run（L Alt+space）
输入 = 进入计算器模式
输入一个包含 e 和多重负号的复杂表达式，例如：
输入
(-(--334e-12) / (900e---1))
此时单独输入 e 并回车
实际输出：0.7182818285（错误，e默认应为 2.71828…）
✔️ Expected Behavior
e should always evaluate to 2.718281828459045… (Euler's number), unaffected by previous calculations.
e 应始终计算为自然常数 2.718281828459045…，不受之前的计算影响。
❌ Actual Behavior
After the above expression, e returns e-2 (≈0.71828) or e-1 and even other value.
The wrong value persists even after closing and reopening PowerToys Run
my way to solve: Deleting cache files restores correct behavior temporarily
执行上述表达式后，e 返回 e-2（约 0.71828）或者 e-1 甚至其他乱七八杂的值
即使关闭并重新打开 PowerToys Run，错误值依然保持
删除缓存文件(可临时恢复正确行为)
