## ◆ cast()

def cast | ( |  | self,
|  |  | val
| ) |  |

    Try to cast `val` as a Bit-Vector.

    >>> b.cast(10)
    10
    >>> b.cast(10).sexpr()
    '#x0000000a'

Reimplemented from SortRef.

## ◆ size()

def size | ( |  | self | ) |

    Return the size (number of bits) of the bit-vector sort `self`.

## ◆ subsort()

def subsort | ( |  | self,

    Return `True` if `self` is a subsort of `other`.

    >>> IntSort().subsort(RealSort())
    True
