Is there a function or operator that I can apply to get the equivalent of the right side of this equation with whole Numbers on the left? f (a^(1/wholeNumberX) , a^(1/wholeNumberY) ) = a^(1.3) Last edited by Sixophrenia; March 21st, 2018 at 09:12 AM.

I think I made a mistake, but it looks like there's enough room in the algebra to accomplish what I was attempting; representations for fractional exponents.
thanks

oh wait.
actually. I can't do that 10/13.
I know that sucks. but it's a limitation of the programming language I'm in. Solidity.

Maybe a Taylor series would work? I don't know. I am barely stringing things together.
I may have to try to find a different way of figuring this out.

If you can do division in this computer, do you think you can use Taylor series. Good luck.

It's just that division requires a number type that can't be directly supported.
No floating point integers in Solidity.

I think I basically have to abstract that with real integers
