---|---|---|

= | x=y | x=y |

+= | x+=y | x=x+y |

-= | x-=y | x=x-y |

*= | x*=y | x=x*y |

/= | x/=y | x=x/y |

.= | x.=y | x=x.y |

%= | x%=y | x=x%y |

### Comparison Operators

Operator | Description | Example |
---|---|---|

== | is equal to | 5==8 returns false |

!= | is not equal | 5!=8 returns true |

<> | is not equal | 5<>8 returns true |

> | is greater than | 5>8 returns false |

< | is less than | 5<8 returns true |

>= | is greater than or equal to | 5>=8 returns false |

<= | is less than or equal to | 5<=8 returns true |

### Logical Operators

Operator | Description | Example |
---|---|---|

&& | and | x=6 y=3 (x < 10 && y > 1) returns true |

|| | or | x=6 y=3 (x==5 || y==5) returns false |

! | not | x=6 y=3 !(x==y) returns true |
