计算变量的写法

黑之翅膀

计算：
+     (加)
-      (减)
*     (乘)
/      (除)
%    (取余数)

加法：
1.

1. a = a + b

复制代码

2.

1. a = 1
   
2. b = 5
   
3. a = a + b

复制代码

（a = 6）


3.

1. $game_variables[a] = 1
   
2. $game_variables[b] = 2
   
3. $game_variables[a] = $game_variables[a] + $game_variables[b]

复制代码

（$game_variables[a] =3）


4.

1. a = 1.0
   
2. b = 2.0
   
3. a = a + b

复制代码

(a = 3.0)

a = 1.0
b = 2
a = a + b
(a = 3.0)


5.

1. $game_variables[a] = 5
   
2. $game_variables[b] = 2
   
3. $game_variables[a] = $game_variables[a] * 1.0
   
4. $game_variables[a] = $game_variables[a] + $game_variables[b]

复制代码

($game_variables[a] = 6.0)


6.

1. a = 1
   
2. b = 2.5
   
3. a = a + b

复制代码

(a = 3.5)

黑之翅膀

a = 3.5
a = a.round
(a = 4)

round   四舍五入

a = 3.5
a = a.to_i
(a = 3)

to_i    取整
对不起，我写错地方了...
