Cast

type conversion

Syntax
Cast(E:OBJECT,T:TYPE):TYPE

Description
This function returns the value of the expression E after converting it to type T. If S and T are types with S < T, then casting from S to T is usually possible.

Example
L := [[1,2],[3,4]];
Type(L);
LIST
-------------------------------
Cast(L,MAT);
Mat([
  [1, 2],
  [3, 4]
])
-------------------------------
L;  -- L is unchanged; it is still a list.
[[1, 2], [3, 4]]
-------------------------------
Use Z/(5)[t];
A := 8;
A;  -- A has type INT
8
-------------------------------
Cast(A,POLY);  -- cast as a polynomial, A = -2 since the coefficient
               -- ring is Z/5Z
-2
-------------------------------
