Contents
Number Value
Numeric value which can be assigned to a variable or used in function parameters.
Arithmetic Operations
Performs the arithmetic operations on the left input with the right input. Then returns that value. Variables can be used to inputs.
- +, -, x, ÷ : add, subtract, multiply, divide. Read more here: https://www.arduino.cc/en/Reference/Arithmetic
- % : modulo. Read more here: https://www.arduino.cc/en/Reference/modulo
- ^ : power. i.e. 2^3 = 2 * 2 * 2 = 8
Trigonometry Function
- sin- Takes the sin of the input and returns it. Read more here: https://www.arduino.cc/en/Reference/Sin
- cos - Takes the cos of the input and returns it. Read more here: https://www.arduino.cc/en/Reference/Cos
- tan - Takes the tan of the input and returns it. Read more here: https://www.arduino.cc/en/Reference/Tan
- asin, acos, atan. Read more here: https://www.arduino.cc/en/Math/H
Number Function
- toInt - Converts the input into an Integer type (https://www.arduino.cc/en/Reference/Int) and returns it. Read more here: https://www.arduino.cc/en/Reference/IntCast
- abs - Takes the absolute value of the input and returns it. Read more here: https://www.arduino.cc/en/reference/abs
- sq - Takes the square of the input and returns it. Read more here: https://www.arduino.cc/en/Reference/Sq
- sqrt - Takes the square root of the input and returns it. Read more here: https://www.arduino.cc/en/Reference/Sqrt
- log - Takes the natural log of the input and returns it: Read more here: https://www.arduino.cc/en/Reference/MathHeader
Max / Min
- max - Takes the max of the two inputs and returns it. Read more here: https://www.arduino.cc/en/Reference/Max
- min - Takes the min of the two inputs and returns it. Read more here: https://www.arduino.cc/en/Reference/Min
Random Integer
Returns a random integer between the two input values.
- min (left input) - lower bound of the random value, inclusive (optional)
- max (right input) - upper bound of the random value, exclusive
Example: random(5, 77) will return a value between 5 and 76.

Constrain
Constrains the Input to the Low and High and returns it.
- Input - Variable or value that will be constrained.
- Low - Lower value that Input will be constrained to.
- High - Upper value that Input will be constrained to.
Example 1: Input is 10, Low is 5, and High is 15. Constrain returns 10.
Example 2: Input is 100, Low is 5, and High is 15. Constrain returns 15.
Example 3: Input is 2, Low is 5, and High is 15. Constrain returns 2.

Map
Re-maps the Input from one range [fromLow , fromHigh] to another range [toLow , toHigh]. Then returns that value.
That is, a value of fromLow would get mapped to toLow, a value of fromHigh to toHigh, values in-between to values in-between, etc.
- Input - Input that will be re-mapped from from range to to range .
- From Range
- fromLow - Low value of the from range
- fromHigh - High value of the from range
- To Range
- toLow - Low value of the to range
- toHigh - High value of the to range
The function that is used is:
Mapped_Output = (Input - fromLow) * (toHigh - toLow) / (fromMax - fromMin) + toLow
