◆ 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.

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
