这篇文章主要介绍了Lua中算术运算符的使用示例,是Lua入门学习中的基础知识,需要的朋友可以参考下
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 )
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
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
