Symbols and Operators

Operators are tools to perform operations on a number. Some operators you might recognise already are +, -, <, etc. Operators are used to affect one or more items. For example, we might compare two items using operators, or add two items together.

Priority

Some operators have a higher priority than others. This means they happen first in a line of code even if they do not appear first. For example:

a = 10 * 30 + 5

In this example, the multiply will happen before the addition, giving a result of 305. This is because the multiplication operation has a higher priority than addition.

When operators have the same priority, they happen in order of appearance. For example:

a = 10 + 30 - 5

In this example, the addition happens before the subtraction because it appears first.

Below are all of the operators in FUZE⁴ Nintendo Switch listed in order of priority. Higher priority operators happen before lower. Operators in the same group have the same priority.

Group 0 - Brackets

Brackets behave in a special way. Anything inside brackets will take place first, even if the operations within the brackets have a lower priority than operations outside them. Of course, operations within the brackets still behave in terms of their normal priority.

( ) Parentheses - Used to change the order of evaluation. Operations inside parentheses will happen before operations on the outside. Parentheses are also used to set the arguments of a function call.

[ ] Square Brackets - Used with arrays to define a number of elements, or to index into an array.

{ } Curly Brackets - Used to define a vector. Empty curly brackets sets default values of { 0, 0, 0, 0 }.

Group 1 - Highest Priority

NOT, ! Not - Performs the logical inversion on a given value. False becomes true, true becomes false. Either NOT or ! can be used.

BNOT, ~ Binary Not - Performs the Not operation on a bitwise basis. Either BNOT or ~ can be used.

Group 2

* Multiply - Used to multiply a value by another.

/ Divide - Used to divide a value by another.

MOD, % Modulo - Used to give the remainder of a division. Either MOD or % can be used.

Group 3

+ Add - Used to add two values together. Also used to join string content together.

- Minus - Used to subtract a value from another. Also used as a sign to indicate a negative number.

<< Shift Left - Used to perform the bit shift operation to the left. Effectively multiplies a value by two for the number of bits shifted.

>> Shift Right - Used to perform the bit shift operation to the right. Effectively divides a value by two for the number of bits shifted.

& Binary And - Performs the and operation on a bitwise basis.

| Binary Or - Performs the or operation on a bitwise basis.

^ Exclusive Or - Used to perform the exclusive or operation

Group 4

== Double Equals - Used to compare two values and determine whether they are exactly equal to each other.

< Less Than - Used to compare two values and determine whether one is less than the other.

<= Less Than or Equal To - Used to compare to values and determine whether one is less than or equal to the other.

> Greater Than - Used to compare two values and determine whether one is greater than the other.

>= Greater Than or Equal To - Used to compare two values and determine whether one is greater than or equal to the other.

!= Not Equal To - Used to compare two values and determine whether they are not equal to each other.

Group 5

AND Logical And - Used to compare two values to determine whether they are both true.

Group 6

OR Logical Or - Used to compare two values to determine whether either are true.

Group 7 - Lowest Priority

= Assign - Used to assign a value to a variable.

+= Plus Equals - Used to perform an addition on the contents of a variable.

-= Minus Equals - Used to perform a subtraction on the contents of a variable.

*= Times Equals - Used to perform a multiplication on the contents of a variable.

/= Divide Equals - Used to perform a division on the contents of a variable.
