The R expression
exp(1)
represents e, and
exp(2)
represents e^2.
This works because exp is the exponentiation function with base e.

-digamma(1) is the Euler's Constant in R.

hey so i learned the e = mc2 theory and i'm writing my code on it but einstein.py needs to round the numbers for some reason?

The "e" is a symbol for base-10 scientific notation. The "e" stands for $\times 10^{\rm exponent}$. So -1.861246e-04 means $-1.861246 \times 10^{-4}$. In fixed-point notation that would be -0.0001861246.
This notation is pretty standard. Even Microsoft Excel understands it, not just R.
I cannot yet comment so this answer will be a response to @Mark L. Stone : OP also stated that he's getting covariance matrix values in the scientific notation. Obviously the negative value must be one of the covariances.
To not be completely OT I will just add that working with scientific notation to me looks a bit clunky(especially if you are publishing the results). To supress the notation in R use the command options(scipen=alpha) where alpha is the maximum number of digits for the result to be still expressed in fixed notation.
Hi guys! I just started learning R and I was trying some basic percentage calculations and I don't know why but my RStudio is showing the results like this instead of " 0.00039975146 " as I was expecting.
Does anyone know how to fix this?
