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
