Because it is an integer, there is no difference in C# between 0 and -0 - the internal representation is the same: 32 bits which are all zero.

For floating point values the internal representation of 0.0 and -0.0 is different, but they are equal values and an equality test will confirm that.

It's possible it was originally "-1" and the author changed the number and forgot the sign.
