# List of Claripy Operations

Name | Description | Example |

LShR | Logically shifts an expression to the right. (the default shifts are arithmetic) | `x.LShR(10)` |

RotateLeft | Rotates an expression left | `x.RotateLeft(8)` |

RotateRight | Rotates an expression right | `x.RotateRight(8)` |

And | Logical And (on boolean expressions) | `solver.And(x == y, x > 0)` |

Or | Logical Or (on boolean expressions) | `solver.Or(x == y, y < 10)` |

Not | Logical Not (on a boolean expression) | `solver.Not(x == y)` is the same as `x != y` |

If | An If-then-else | Choose the maximum of two expressions: `solver.If(x > y, x, y)` |

ULE | Unsigned less than or equal to | Check if x is less than or equal to y: `x.ULE(y)` |

ULT | Unsigned less than | Check if x is less than y: `x.ULT(y)` |

UGE | Unsigned greater than or equal to | Check if x is greater than or equal to y: `x.UGE(y)` |

UGT | Unsigned greater than | Check if x is greater than y: `x.UGT(y)` |

SLE | Signed less than or equal to | Check if x is less than or equal to y: `x.SLE(y)` |

SLT | Signed less than | Check if x is less than y: `x.SLT(y)` |

SGE | Signed greater than or equal to | Check if x is greater than or equal to y: `x.SGE(y)` |

SGT | Signed greater than | Check if x is greater than y: `x.SGT(y)` |

TODO: Add the floating point ops

Name | Description | Example |

SignExt | Pad a bitvector on the left with `n` sign bits | `x.sign_extend(n)` |

ZeroExt | Pad a bitvector on the left with `n` zero bits | `x.zero_extend(n)` |

Extract | Extracts the given bits (zero-indexed from the right, inclusive) from an expression. | Extract the least significant byte of x: `x[7:0]` |

Concat | Concatenates any number of expressions together into a new expression. | `x.concat(y, ...)` |

There's a bunch of prepackaged behavior that you

*could*implement by analyzing the ASTs and composing sets of operations, but here's an easier way to do it:- You can chop a bitvector into a list of chunks of
`n`

bits with`val.chop(n)`

- You can endian-reverse a bitvector with
`x.reversed`

- You can get the width of a bitvector in bits with
`val.length`

- You can test if an AST has any symbolic components with
`val.symbolic`

- You can get a set of the names of all the symbolic variables implicated in the construction of an AST with
`val.variables`
