Variable and Data Types

Data Types

Mufi-Lang has the following data types:

Name	Size	Type
int	2/4 bytes	Primitive
double	8 bytes	Primitive
bool	1 byte	Primitive
complex	16 bytes	Primitive
string	variable	Object
fvec	variable	Object
linked list	variable	Object
hash table	variable	Object

Array and Matrix Removal

The array and matrix data types have been removed from Mufi-Lang as of version 0.8.0. We are working on having fvec be the default array type for numerical types as it can take advantage of SIMD instructions and is more memory efficient. The matrix type will return once we have done the research of the best implementation and build it to take advantage of SIMD operations.

Variables

Variables are used to store data, and are declared using the var keyword. You may choose to initialize the variable with a value or not. If you do not initialize the variable, it will be initialized with nil.

var a = 10;
var b; // or var b = nil;

Global and Local Scopes

Variables can be declared in the global scope or local scope. Global variables are declared outside of any function and can be accessed from anywhere in the program. Local variables are declared inside a function and can only be accessed within that function.

var a = 10; // Global
fun foo() {
    var b = 20; // Local
}
print b; // Undefined variable 'b'.
