Operators#

Introduction#

The Operators blocks in VEXcode GO handle mathematical calculations and string manipulations. These blocks allow for performing arithmetic, evaluating conditions, and processing text. Below is a list of available blocks:

Math – Perform calculations and evaluate numerical conditions.

  • math operator – Performs addition, subtraction, multiplication, or division.

  • comparison operator – Compares two values using greater than, less than, or equal operators.

  • logical operator – Evaluates multiple conditions using and or or.

  • not operator – Inverts a Boolean value.

  • range operator – Checks if a number falls within a range.

  • pick random – Generates a random number within a specified range.

  • round number – Rounds a number to the nearest whole number.

  • math functions – Applies operations such as square root, trigonometry, logarithms, and exponentiation.

  • remainder – Returns the remainder of a division operation.

Strings – Manipulate and analyze text.

  • join – Combines two strings into one.

  • letter – Extracts a character from a string by position.

  • length – Returns the number of characters in a string.

  • contains – Checks if a string includes a specific word or character.

  • convert – Converts a number into text, a whole number, or a decimal.

Math#

math operator#

The math operator block performs basic arithmetic on the values placed on either side. 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 block.

The Math operator reporter block.#
([0] [math_plus v] [0])

Parameters

Description

value 1

The first number used in the operation.

operator

The mathematical operator to use:

  • + - Addition
  • - - Subtraction
  • * - Multiplication
  • / - Division

value 2

The second number used in the operation.

Example

cuando empezó :: hat events
[Perform basic addition and show two decimal places.]
establecer la precisión de impresión a [0.01 v]
imprimir ([10] [math_plus v] [10.5]) ▶

comparison operator#

The comparison operator block returns a Boolean indicating 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).

The Comparison operator Boolean block.#
<[0] [math_equal v] [0]>

Parameter

Description

value 1

The first value to compare.

operator

The comparison to use:

  • = - Equal to
  • < - Less than
  • - Less than or equal to
  • > - Greater than
  • - Greater than or equal to

value 2

The second value to compare.

Example

cuando empezó :: hat events
[Turn right until the heading reaches 90 degrees.]

logical operator#

The logical operator block returns a Boolean indicating whether the logical condition between multiple values is true or false.

  • True – The logic condition is met.

  • False – The logic condition is not met.

The Logical Operator Boolean block.#
<<> [and v] <>>

Parameter

Description

condition 1

The first Boolean condition to evaluate.

operator

The logical operator to use:

  • and - Returns True if both conditions are True.
  • or - Returns True if at least one condition is True.

condition 2

The second Boolean condition to evaluate.

Example

cuando empezó :: hat events
[Approach an object until it touches the LED Bumper..]
para siempre
unidad [adelante v]
si <<¿El ojo encontró un objeto?> [and v] <no <[LEDBumper 1 v] presionado?>>> entonces

fin
fin

not operator#

The not operator block inverts the result of a Boolean block. If the input is True, it returns False, and if the input is False, it returns True.

  • True – The input condition would normally return False.

  • False – The input condition would normally return True.

The Not Operator Boolean block.#
<no <>>

Parameter

range operator#

The range operator block returns a Boolean indicating whether a value falls within a specified range.

  • True – If the value is within the range.

  • False – If the value is outside the range.

The Range Operator Boolean block.#
<[0] [math_less_than v] [0] [math_less_than v] [0]>

Parameter

Description

first operator

The comparison operator to use:

  • < - Less than
  • ≤ - Less than or equal to
