Return `true` if the specified `lhs` and `rhs` have the same value, and `false` otherwise. Two `Decimal32` 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 `Decimal32` objects 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/Decimal32.adoc[Decimal32] 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)

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

Note that a NaN is never equal to anything, including itself: ` Decimal32 aNaN = std::numeric_limits<Decimal32>::quiet_NaN(); assert(!(aNan == aNan)); `
