    Hi,
    I'm debugging my code line by line and I see values like these in the inspector. What do they mean? And are they essentially zero?

    What you're seeing is called the scientific notation.

    -3.3438327e-06

    equals

    -3.3438327 x 10^-6,

    which is

    -0.0000033438327

    which is very close to zero.

    You usually end up with values like this, because of the limited precision of floating point values represented in a computer, so after doing some math, results often end up being slightly off.
