The Greater than block reports True when the first value is larger than the second value and False when the first value is smaller than or equal to the second value.

The Greater than Boolean block reports a true or false value and fits in blocks with hexagonal (six-sided) spaces.

In this example, the 123 Robot will move in forward for 3 steps, because 50 > 0 returns True.

A visual programming block sequence that begins with a yellow 'when started' block. Below it is a yellow 'if-then' block with a condition. The condition is a green, diamond-shaped comparison block that checks if '50 > 0.' If the condition is met, the first action is to 'drive forward for 3 steps' using a blue block. This sequence will cause the robot to move forward if the condition is true.

Less than #

The Equal to block is used to report if the first value is the same as, or equal to, the second value.

A green, diamond-shaped block from a visual programming interface featuring two input fields with the values '0' and '50,' separated by an equal sign ('='). This block represents a comparison operation where the first value, 0, is checked to see if it is equal to the second value, 50.

The Equal to block can accept decimals, integers, or numeric blocks.

The Equal to block reports True when the two values are exactly the same and reports False when the two values are not the same.

The Equal to Boolean block reports a true or false value and fits in blocks with hexagonal (six-sided) spaces.

In this example, the 123 Robot will move forward for 20 mm, because 20 = 20 returns True.

A visual programming block sequence that begins with a yellow 'when started' block. Below it is a yellow 'if-then' block with a condition. The condition is a green, diamond-shaped comparison block that checks if '0 = 50.' If the condition is met, the first action is to 'drive forward for 3 steps' using a blue block.

And #

The And block is used to report if two Boolean conditions are both true.

A green, diamond-shaped block from a visual programming interface labeled 'and.' The block has two open hexagonal slots on either side where additional blocks can be inserted. This block is used to represent a logical 'and' operation, combining two conditions.

The And block reports True when both conditions are true and reports False when one, or both, of the conditions are false.

In this example, if the Eye Sensor detects a red object and the 123 Robot is moving at the same time, the 123 Robot will stop moving. Otherwise, the 123 Robot will keep moving forward. The Not block is used to check if the 123 Robot is moving, by saying when the 123 Robot is Not done driving.

Round #

The Round block is used to round the inputted value to the nearest integer.

A green, rounded block from a visual coding interface labeled 'round.' The block contains an input field on the right side with the number '0.' This block is used to round the value entered in the input field to the nearest integer.
