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:
复制代码 代码如下: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:
复制代码 代码如下: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
