Arithmetic Operators¶

Syntax:

(operator operand)                          ; Unary operators
(operator operand1 operand2)                ; Binary operators
(operator operand1 operand2 ... operandn)   ; N-ary operators

Addition +¶

Adds two or more values together:

; Result will be 40.
(= Result (+ 30 10))
; Result will be 60
(= Result (+ 30 10 20))

Subtraction -¶

Subtracts two values from each other:

; Result will be 20
(= Result (- 30 10))

Multiplication *¶

Multiplies two or more values together:

; Result will be 300
(= Result (* 30 10))
; Result will be 6000
(= Result (* 30 10 20))

Division ¶

Divides one number by another:

; Result will be 3
(= Result (/ 30 10))

Note that floating point numbers are not supported in SCI, so this is always an integer division.

Modulus mod¶

Divides two values and returns the remainder:

; Result will be 5
(= Result (mod 35 10))

Increment ++¶

Increments a variable or property:

(= Result 10)
(++ Result)     ; Result is now 11

Decrement –¶

Decrements a variable or property:

(= Result 10)
(-- Result)     ; Result is now 9
