Return `false` if the specified `lhs` and `rhs` have the same value, and `true` otherwise. Two decimal objects have the same value if the `compareQuietEqual` operation (IEEE‐754 defined, non‐total ordering comparison) considers the underlying IEEE representations equal. In other words, two decimal objects have the same value if:

    xref:BloombergLP/bdldfp/DecimalImpUtil/ValueType32.adoc[ValueType32] rhs);

== Description

* both have a zero value (positive or negative), or * both have the same infinity value (both positive or negative), or * both have the value of a real number that are equal, even if they are represented differently (cohorts have the same value)

If either or both operands are signaling NaN, store the value of the macro `EDOM` into `errno` and return `false`.
