Operadores#
Introducción#
The Operator blocks in VEXcode AIM help the robot work with numbers and words. These blocks can solve math problems, compare values, evaluating if conditions are true or false, and working with strings. Strings can be used to print values and words.
A continuación se muestra una lista de bloques disponibles:
operador matemático – Realiza suma, resta, multiplicación o división.
comparison operator – Compares two values using greater than, less than, or equal to operators.
operador lógico – Evalúa múltiples condiciones usando y o o.
operador no – Invierte un valor booleano.
operador de rango – Comprueba si un número cae dentro de un rango.
pick random – Genera un número aleatorio dentro de un rango especificado.
número redondo – Redondea un número al número entero más cercano.
funciones matemáticas – Aplica operaciones como raíz cuadrada, trigonometría, logaritmos y exponenciación.
atan2 – Calcula la tangente inversa de y/x.
remainder – Reports the remainder of a division operation.
join – Combina dos cadenas en una.
letra – Extrae un carácter de una cadena por posición.
length – Reports the number of characters in a string.
contiene – Comprueba si una cadena incluye una palabra o carácter específico.
convert – Convierte un número en texto, un número entero o un decimal.
operador matemático#
The math operator reporter block performs basic math operations on the values placed on either side of the operator. It returns a result based on the project’s print precision, which defaults to 0 decimal places but can be adjusted using the set print precision on screen or set print precision on console blocks.
([0] [math_plus v] [0])

operador de comparación#
The comparison operator Boolean block reports whether the comparison between two values is True or False.
True – The comparison is correct (e.g., 5 > 3 returns True).
False – The comparison is incorrect (e.g., 2 ≥ 5 returns False).
<[0] [math_equal v] [0]>

no operador#
The not operator Boolean block inverts the result of a Boolean block. If the input is True, it reports False, and if the input is False, it reports True.
