Detailed Description

A Sort is essentially a type. Every Z3 expression has a sort. A sort is an AST node.

◆ cast()

cast (   self,
  val 
)
Try to cast `val` as an element of sort `self`.

This method is used in Z3Py to convert Python objects such as integers,
floats, longs and strings into Z3 expressions.

>>> x = Int('x')
>>> RealSort().cast(x)

Return a unique identifier for t. The identifier is unique up to structural equality....

◆ kind()

kind (   self)
