Factorials/Binomial (oguzkurt) #147

Open bartsnapp opened 7 years ago

bartsnapp commented 7 years ago

When a problem has 100!/30! as an answer, the system accepts it. But if the outcome gets larger, the system does not accept it. Can you give me an idea as to how large an answer does the system accept.

I personally like to write problems whose answers are large so that they will not be tempted to find the answer via calculator. Instead they will use the parsing ability within the answer box! This forces them to think in combinations and permutations. At least, I hope so!

It looks like the system is using double-precision number (https://github.com/kisonecat/math-expressions/blob/master/lib/expression/equality/complex.js). The limit is within: 171! < MAX < 172!
