+、-、*、/、%的使用

local intResult = 1 + 2
print(intResult) --3


intResult = intResult - 1
print(intResult) --2


intResult = intResult * 2
print(intResult) --4


intResult = intResult / 2
print(intResult) --2


intResult = intResult + 8
intResult = intResult % 7
print(intResult) --3


print("-------")
--声明一个浮点型变量
local doubleResult = 10.6
print(doubleResult)--10.6


doubleResult = doubleResult - 1
print(doubleResult) --9.6


doubleResult = doubleResult * 2
print(doubleResult) --19.2


doubleResult = doubleResult / 2
print(doubleResult) --9.6


doubleResult = doubleResult + 8
doubleResult = doubleResult % 7
print(doubleResult) --3.6
