Statistics in R, euler constant?
Just to extend the other comments that already helped you, I want to mention that this isn't the euler constant. "e" means exponent of 10. This is scientific notation, so basically the number after e tells how many digits the decimal point has been shiftet left or right. More on reddit.com

Scientific notation in R | DataKwery
July 11, 2020 - R uses scientific e notation where e tells you to multiple the base number by 10 raised to the power shown. Let’s start with the number 28. Scientific notation adds a decimal after the first number before applying the system.

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.

May 2, 2024 - Consider an equation of the form $e^x = b$. To solve for $x$, you would typically take the logarithm of both sides. In R, this is straightforward: # Define b b <- 10 # Solve for x using logarithms x <- log(b) # Display the solution print(x) This code snippet elegantly illustrates solving an exponential equation, demonstrating R's prowess in handling both simple and complex mathematical operations.
