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 and returns it. (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 [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
