Lua中算术运算符的使用示例

下表列出了所有的Lua语言支持的算术运算符。假设变量A持有10和变量B持有20，则：

 例子

试试下面的例子就明白了所有的Lua编程语言提供了算术运算符：

a = 21

b = 10

c = a + b

print("Line 1 - Value of c is ", c )

c = a - b

print("Line 2 - Value of c is ", c )

c = a * b

print("Line 3 - Value of c is ", c )

c = a / b

print("Line 4 - Value of c is ", c )

c = a % b

print("Line 5 - Value of c is ", c )

c = a^2

print("Line 6 - Value of c is ", c )

c = -a

print("Line 7 - Value of c is ", c )

当执行上面的程序，它会产生以下结果：

Line 1 - Value of c is  31

Line 2 - Value of c is  11

Line 3 - Value of c is  210

Line 4 - Value of c is  2.1

Line 5 - Value of c is  1

Line 6 - Value of c is  441

Line 7 - Value of c is  -21
