Operators

Arithmetic

Operator	Description	Example
+	Adds two numeric values or concatenates text.	numero total = a + b
-	Subtracts the second operand from the first.	entero diferencia = a - b
*	Multiplication.	entero producto = a * b
/	Division. For integers, division is integer division.	entero cociente = a / b
%	Remainder or modulo.	entero residuo = a % b

entero suma = 5 + 3
texto combinado = "Hola" + " Quetzal"

Relational

Operator	Description
==	Equality.
!=	Inequality.
>	Greater than.
<	Less than.
>=	Greater than or equal.
<=	Less than or equal.

log es_mayor = 10 > 5
log es_igual = "texto" == "texto"

Logical

Quetzal supports both symbolic operators (&&, ||, !) and their Spanish equivalents (y, o, no).

log acceso = (usuario.autenticado y !usuario.bloqueado)
log disponible = (stock > 0) o (pedido_en_camino == verdadero)
log negado = no acceso

Non-boolean values are automatically converted to log following interpreter rules (e.g., empty lists are falso).

Assignment

Operator	Description
=	Simple assignment.
+=	Add and assign.
-=	Subtract and assign.
*=	Multiply and assign.
/=	Divide and assign.
%=	Calculate remainder and assign.

entero var acumulado = 0
acumulado += 5
acumulado -= 2

Increment and Decrement

The ++ and -- operators are available in postfix form.

entero var contador = 0
contador++
contador--

Ternary Operator

The form condition ? value_if_true : value_if_false is available for quick evaluations.

entero numero = -10
entero absoluto = numero < 0 ? -numero : numero

Operators for Lists and JSON

Lists and jsn values provide methods instead of specific operators. For example, lista.concatenar(otra_lista) or json.fusionar(otro_json). See the data types sections for more information.

Precedence

1. Function calls and member access.
2. Unary operators (no, !, ++, --).
3. Multiplication and division.
4. Addition and subtraction.
5. Comparisons.
6. Logical operators (y, o).
7. Assignments (=, +=, etc.).

Use parentheses to clarify intent when combining multiple operators.

// Arithmetic operators
entero suma(entero a, entero b) {
    retornar a + b
}

entero resta(entero a, entero b) {
    retornar a - b
}

// Logical operators
log es_verdadero(log valor) {
    retornar valor
}

log es_falso(log valor) {
    retornar !valor
}

// Comparison operators
log es_igual(entero a, entero b) {
    retornar a == b
}

log es_diferente(entero a, entero b) {
    retornar a != b
}

log es_mayor(entero a, entero b) {
    retornar a > b
}

log es_menor(entero a, entero b) {
    retornar a < b
}

// Compound operators
entero suma_compuesta(entero var valor, entero incremento) {
    valor += incremento
    retornar valor
}

// Run functions to test operators
entero resultado_suma = suma(5, 10)
entero resultado_resta = resta(10, 5)
log resultado_es_igual = es_igual(5, 5)
entero resultado_suma_compuesta = suma_compuesta(5, 10)
