Return `true` if the specified `lhs` and `rhs` do not have the same value, and `false` otherwise. Two decimal objects do not have the same value if the `compareQuietEqual` operation (IEEE‐754 defined, non‐total ordering comparison) considers the underlying IEEE representations not equal. In other words, two decimal objects do not have the same value if:

== Synopsis

Declared in `<bdldfp_decimal.h>`

[source,cpp,subs="verbatim,replacements,macros,-callouts"]
----
bool
operator!=(
    xref:BloombergLP/bdldfp/Decimal32.adoc[Decimal32] lhs,
    xref:BloombergLP/bdldfp/Decimal64.adoc[Decimal64] rhs);
----

== Description

* both are NaN, or * one has zero value (positive or negative) and the other does not, or * one has the value of positive infinity and the other does not, or * one has the value of negative infinity and the other does not, or * both have the value of a real number that are not equal, regardless of their representation (cohorts are equal)

This operation stores the value of the macro `EDOM` into `errno` if either or both operands are signaling NaN.
