cast()

def cast	(		self,
			val
	)

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

>>> b = BitVecSort(32)
>>> b.cast(10)
10
>>> b.cast(10).sexpr()
'#x0000000a'

Reimplemented from SortRef.

size()

def size

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`.
