   **Type annotations recommended!** While optional, they catch errors before runtime and make code self-documenting.

+#### Typecasting
+In many cases, Luau does typecasting automatically. Here's how to do it explicitly:

+```lsl
+(integer)"-4.4";
+(float)"25.5";
+(string)99.9;
+(vector)"<10, 20, 30>";
+(rotation)"<0, 0, 0, 1>";
+(key)"700843d3-0d15-c427-81ab-e9c8a0dcdb1e";
+(list)"hello"; // equivilant to ["hello"]
+```
+</Fragment>
+<Fragment slot="Lua">
+```luau
+(math.modf(tonumber("-4.4") or 0)) -- extra parentheses sometimes necessary
+tonumber("25.5") or 0
+tostring(99.9)
+tovector("<10, 20, 30>") or ZERO_VECTOR
+toquaternion("<0, 0, 0, 1>") or ZERO_ROTATION
+uuid("700843d3-0d15-c427-81ab-e9c8a0dcdb1e") or NULL_KEY
+{"hello"}  -- table, not list
+```
+</Fragment>
+</CodeComparison>
+LSL and Lua typecasts return different results on invalid input: LSL returns "zero"; Lua returns `nil`. The Lua examples include an `or` expressions that converts `nil` to what LSL typecast would have returned
