Dear Andrew,
FrontEndExecute[{HelpBrowserLookup["RefGuide","Equal"]}]
I copy from there
"Approximate numbers are considered equal if they differ in at most
their last eight binary digits (roughly their last two decimal digits).
2 == 2. gives True ".
Use SameQ
{3. == 3, 3. === 3}
{True, False}
Regards
Dimitris
