Dangerous Floating-Point Comparisons — When Zero Isn't Really ...
In floating-point representation, both positive zero (+0) and negative zero (-0) exist, and while they are typically treated as equal for most arithmetic operations, they have distinct binary representations. The IEEE 754 standard defines +0 and -0 using the same exponent and significand (both set to zero), but with different sign bits. The sign bit for +0 is 0, and for -0, it is 1.
