This trait struct is a metafunction that determines whether the specified parameter t_TYPE is bitwise EqualityComparable. If IsBitwiseEqualityComparable<t_TYPE> is derived from true_type then t_TYPE is bitwise EqualityComparable. Otherwise, bitwise equality comparability cannot be inferred for t_TYPE. This trait can be associated with a bitwise EqualityComparable user‐defined class by specializing this class or by using the BSLMF_NESTED_TRAIT_DECLARATION macro.

Revert of {DRQS 143286899}. Once clients are fixed, change to false. Explicit specialization to confirm that floating point types are not bitwise EqualityComparable, as they typically have specific problematic values: NaNs do not compare equal with themselves, and there may be multiple representations for zero (with negative zero). |
