# Supported Operations

The list of supported operations by the homomorphic Booleans is:

Operation Name | type |
---|---|

`not` | Unary |

`and` | Binary |

`or` | Binary |

`xor` | Binary |

`nor` | Binary |

`xnor` | Binary |

`cmux` | Ternary |

In TFHE-rs, shortint represents short unsigned integers encoded over a maximum of 8 bits. A complete homomorphic arithmetic is provided, along with the possibility to compute univariate and bi-variate functions. Some operations are only available for integers up to 4 bits. More technical details can be found here.

The list of supported operations is:

Operation name | Type |
---|---|

Negation | Unary |

Addition | Binary |

Subtraction | Binary |

Multiplication | Binary |

Division* | Binary |

Modular reduction | Binary |

Comparisons | Binary |

Left/Right Shift | Binary |

And | Binary |

Or | Binary |

Xor | Binary |

Exact Function Evaluation | Unary/Binary |

The division operation implements a subtlety: since data is encrypted, it might be possible to compute a division by 0. The division is tweaked so that dividing by 0 returns 0.

In TFHE-rs, integers represent unsigned integers up to 256 bits. They are encoded using Radix representations by default (more details here).

The list of supported operations is:

Operation name | Type |
---|---|

Negation | Unary |

Addition | Binary |

Subtraction | Binary |

Multiplication | Binary |

Bitwise OR, AND, XOR | Binary |

Equality | Binary |

Left/Right Shift | Binary |

Comparisons `<` ,`<=` ,`>` , `>=` | Binary |

Min, Max | Binary |
