EV3 DATA OPERATIONS BLOCKS GUIDE : Oakview Preparatory School Yonkers NY

Blocks	Description	Inputs	Outputs
	Variable: Block allows you to read or write a variable in the program. The variable with the data is stored in the brick if you want to use it again. If you want more information, go to this link: Variable.	Variable Name: Any text. Value: Text, Numeric, Logic, Numeric Array, Logic Array.	Value: Text, Numeric, Logic, Numeric Array, Logic Array.
	Constant: A value that you can use throughout your program. Once you change the value, the variable will change through the entire program! If you want more information, go to this link: Constant.	Value: Text, number, boolean.	Value: Text, Numeric, Logic, Numeric Array, Logic Array.
	Array Operations: Block does operations on the Numeric Array and Logic Array data types. If you want more information, go to this link: Array Operations.	Array In: Numeric array or boolean. Value: Numeric or Logic Index: First Element (0), Second Element (1), Last Element (Length-1).	Array Out: Any numeric array or boolean. Value: Numeric Array or Boolean Length: Numeric
	Logic Operations: Block takes the inputs that are True / False and produces a True / False output. (See more info)	Mode: AND, OR, XOR, NOT A: True / False B: False / False	Result: Boolean
	Math Performs a math calculation on its inputs, and outputs the result. (See more info)	Mode: Add, Subtract, Multiply, Divide, Absolute Value, Square Root, Exponent, Advanced A: Number(First operand/Base Value of Exponent) B: Number(Second operand) N: Number(Exponent Value) C: Number(for Advanced Mode) D: Number(for Advanced Mode)	Result: Number
	Round Rounds a decimal number up, down, or to the nearest integer value. You can also truncate a number to a certain number of decimal places.	Input: Number Number of Decimals: Number	Result: Number
	Compare The Compare block compares two numbers to find out whether they are equal, or which number is greater.	A: Number B: Number	Result: Logic
	Range The Range block tests whether a number is inside or outside a specified numerical range.	Test Value: Number Lower Bound: Number Upper Bound: Number	Result: Logic
	Text The Text block can combine up to three text strings into one text string.	A: Text B: Text C: Text	Result: Text
	Random The Random block can output a random Numeric or Logic value.	Lower Bounds: Number Upper Bound: Number Probability of True: 0-100	Value: Number or Logic
