◆ cast()

cast ( self,

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

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

◆ size()

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

>>> b = BitVecSort(32)
>>> b.size()
32

unsigned Z3_API Z3_get_bv_sort_size(Z3_context c, Z3_sort t)
Return the size of the given bit-vector sort.

◆ subsort()

subsort ( self,
other )
Return `True` if `self` is a subsort of `other`.

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