◆ cast()

cast	(		self,
			val )

Try to cast `val` as a Boolean.

>>> x = BoolSort().cast(True)
>>> x
True
>>> is_expr(x)
True
>>> is_expr(True)
False
>>> x.sort()
Bool

Reimplemented from SortRef.

◆ is_bool()

is_bool ( self )

Definition at line 1594 of file z3py.py.

    def is_bool(self):
        return True

◆ is_int()

is_int ( self )

Definition at line 1591 of file z3py.py.

    def is_int(self):
        return True
 

Referenced by IntNumRef.as_long(), and ArithSortRef.subsort().

◆ subsort()

subsort	(		self,
			other )

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

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