Numeric calculation using floating point values
can generate imprecise results because of rounding errors.
As a result, two different calculations might generate
numbers that are mathematically equal, but have slightly
different bit representations that do not translate to the
same mathematically-equal values. As a result, an equality
test or other comparison might produce unexpected
results.
This issue can prevent the product from running reliably. If the relevant code is reachable by an attacker, then this reliability problem might introduce a vulnerability.
