About this project

What does Clever Hans add?

horse named calculator

How to use the mod:

  • Approach a horse.
  • Say "Horse!" in chat to get its attention.
  • While you have the horse's attention, ask it a math problem. Examples:
  • Calculate the sum of 5 and 3!
  • Calculate the product of 4 and 7.3!
  • Calculate 2 to the power of 10!
  • Calculate the cube root of 81! (👀)
  • The horse will stomp for a bit and then give you your result

Your message must have proper capitalization and include an exclamation point at the end.

Currently supported operations:
Basic arithmetic:

  • sum (+)
  • product (*)
  • difference (-)
  • quotient (/)
  • power (a to the power of b)
    Roots:
  • square root (2nd root)
  • cube root (3rd root)
  • nth root (4th, 5th, etc.)
    Trigonometry:
  • sine, cosine, tangent
  • arcsine / inverse sine
  • arccosine / inverse cosine
  • arctangent / inverse tangent
  • ! You can specify deg or rad after the number (ex: "Calculate the inverse cosine of 0.5 rad!"), but if you do not, it will default to degrees.
  • !! Just saying "sin", "cos", "tan", "asin", "acos", and "atan" instead of their fully spelled-out counterparts will not work.

If a horse can't produce a valid response (i.e. you inputted an incorrect number of arguments, you attempted to asin/acos a number greater than 1 or less than -1, you requested an invalid operation etc.), it will explode
