That makes more sense than the other thing I tried to read on signed zeros

This might be helpful: Negative Binary Numbers. Two of the three representations, sign-and-magnitude and ones-complement, can represent negative zero. Twos-complement, the most common, cannot represent negative zero.

The above discussion leaves out the complexity of floating point numbers that usually have three separate components: a sign, a "value", and an "exponent". Because (usually) the sign is separate from the number is it similar to sign-and-magnitude representation. See https://floating-point-gui.de/formats/fp/ for more explanation.
