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 ". InputForm[1`2 ] 1.`1.9999999999999998 Precision[%] 2. Use SameQ {3. == 3, 3. === 3} {True, False} Regards Dimitris
