# ➗ Mathematical operations

Those operations let you apply a new value to a variable through the Assign bloc

or verify a condition through the Condition bloc.

x + y

Addition

(y is added to x)

x - y

Subtraction

(y is subtracted from x)

x * y

Multiplication

(x is multiplied by y)

x / y

Division

(x is divided by y)

x == y

Equality

(x equals y)

x < y

Strict inferiority

(x is less than y)

x > y

Strict superiority

(x is greater than y)

x <= y

Inferiority

(x is less than or equal to y)

x >= y

Superiority

(x is greater than or equal to y)

Attention:

Be careful not to accidentally use the = sign (e.g., if the = sign is unique).

x=10

The single equal sign is the operator for assigning a value, and sets the

value from x to 10 (i.e. puts the value 10 in variable x). Be sure to use the instead the double sign equals == (i.e. if (x==10), the == being the operator comparison logic, and which tests whether x is indeed equal to 10 or not).

Unary:

NOT x (can be written !x)

Inverse logic

(denotes the inverse of x if x is boolean, e.g. NOT true == false)

Calculations :

x y

Power (can be written x^y)

(x is multiplied by x, y times)

x % y

Remainder of the Euclidean division (called "modulo")

(x % y is equivalent to what remains of the division of x by y. Ex: 12 % 5 == 2)

Comparison :

x != y

Inequality

(x is different from y)

x !== y

Strict inequality (! ==)

(x is different from y or has a different type)

===

Strict equality

(x is equal to y and has the same type)

x > 3 && y < 2

AND (can also be written AND)

_(The operation is true if both conditions are true at the same time).

_

x > 3 || y < 2

OR (can also be written OR)

_(The operation is true if at least one of the two conditions is true).

_

x > 3 XOR y < 2

OR exclusive

(The operation is true if one of the two conditions is true and the other is false).

Syntax:

( )

Parenthesis

_(Used to prioritize calculations)

_

Period (replaces the usual comma)

PlayerName == "Stone"

The "" identifies whether text is a value (and is enclosed in quotation marks) or a variable (without quotation marks).

or verify a condition through the Condition bloc.
