Calculate (vuo.math.calculate)

Calculates the value of a math expression or formula.

• Expression — A math expression or formula, for example:
  • distance / time
  • avg(a, b, c)
  • PI * r^2
  • area = width * height
• Values — The numbers to substitute in place of the variables in Expression.
• Result — The number calculated from Expression.

The math expression may contain one or more input variables — names like Distance, Time, or A that are replaced with the numbers in Values.

Optionally, the math expression may contain an output variable — a name for the calculated result, to help you remember what it represents. If there’s an output variable, the math expression should have a = sign (assignment operator) with the output variable on the left and the input variables on the right. For example, in the expression area = width * height, the output variable is Area and the input variables are Width and Height.

The math expressions may contain:

• Numbers
• Parentheses — for order of operations
  • ( and )
• Constants — names that represent a certain number
  • P I — π, approximately 3.14
• Operators
  • + — addition
  • - — subtraction
  • * — multiplication
  • / — division
  • ^ — power/exponent
  • % — modulus
  • < — less than
  • > — greater than
  • <= — less than or equal
  • >= - greater than or equal
  • == — equal
  • != — not equal
  • && — logical and
  • || — logical or
  • ?: — if-then-else, for example: score > 100 ? bonus : 0
• Functions
  • Avg — average of a list of numbers
  • Sum — sum of a list of numbers
  • Min — minimum of a list of numbers
  • Max — maximum of a list of numbers
  • Abs — absolute value
  • Rint — round to the nearest integer
  • Sign — -1 if negative, 1 if positive
  • Sqrt — square root
  • Exp — the mathematical constant e raised to a power
  • Ln — logarithm to base e
  • Log or Log 10 — logarithm to base 10
  • Log 2 — logarithm to base 2
  • Deg 2rad — convert degrees to radians
  • Rad 2deg — convert radians to degrees
  • Trigonometry — for numbers in degrees
    • Sin, Cos, Tan
    • Asin, Acos, Atan
    • Sinh, Cosh, Tanh
    • Asinh, Acosh, Atanh
