Arithmetic Operators

Morph supports standard arithmetic operations plus a special matrix multiplication operator.

Operators​

OperatorDescriptionExample
+Additiona + b
-Subtractiona - b
*Multiplicationa * b
/Divisiona / b
@Matrix multiplicationA @ B
++Incrementi++
--Decrementi--

Basic Arithmetic​

x is 10;
y is 3;

sum is x + y;       // 13
diff is x - y;      // 7
product is x * y;   // 30
quotient is x / y;  // 3

Increment and Decrement​

counter is 0;
counter++;          // counter is now 1
counter--;          // counter is now 0

These are commonly used in for loops:

for(i is 0; i < 10; i++) {
    Print(i);
}

Matrix Multiplication (@)​

The @ operator performs matrix multiplication on tensors:

A is Tensor<float>.Random(2, 2);
B is Tensor<float>.Random(2, 2);
C is A @ B;     // matrix multiplication

See Tensor Operations for details.

Operator Precedence​

From highest to lowest:

  1. ! (not), unary -
  2. *, /, @
  3. +, -
  4. ==, !=, >, <, >=, <=
  5. &&
  6. ||

Use parentheses to override precedence:

result is (a + b) * c;
