-0.0 = 0 +0.0 = 0 Hence -0.0 = +0.0 right ?

  Yup - both of the bit patterns for 754 here were assigned the value of 0 and the standard instructed comparison operators to treat the two values as equal. The bit patterns for both -0.0 and +0.0 are assigned to the same real world value - there is no reason to distinguish them outside of circuits that actually execute floating point arithmetic.

    it's important to distinguish them in programs written for those circuits and in compilers that transform those programs because they have significantly and intentionally different behavior
