Dmod 12 //free\\

You cannot compute DMOD 12(0) directly—it is not a number. Naive finite differencing produces nonsense (infinite or NaN values). For example, the central difference formula for the 12th derivative diverges as step size → 0 unless the function is 12x differentiable, which |x| is not.

I received the DMOD-12 as a review sample. All opinions are my own after two weeks of testing. dmod 12

Ongoing research involving DMOD 12 includes: You cannot compute DMOD 12(0) directly—it is not a number

At x = 0 , the derivative is undefined in the classical sense. dmod 12
