Arithmetic operator

Lua’s arithmetic operators are shown in the following table:

Arithmetic operator | Description |
---|---|

+ | addition |

- | subtraction |

* | multiplication |

/ | division |

^ | exponential |

% | modular |

Sample code:

`Print (1 + 2) - > Print 3`

Print (5/10) - > Print 0.5. This is Lua different from C.

Print (5.0/10) - > Print 0.5. The result of floating-point division is floating-point number.

Print (2 ^ 10) - > Print 1024. Find the 10 th power of 2

Localnum = 1357

Print (num%) 2 - > Print 1

Print ((num%) 2) == 1) --> print true. Judging whether num is odd

Print ((num% 5) == 0) --> print false. Judging whether num can be 5 integers
