Happy {$EXCESSPRECISION OFF}!

DelphiTools – Just a notice: I’ve updated the XE2 single-precision floating point article after using the (up to now) undocumented {$EXCESSPRECISION OFF} directive, thanks to Allen Bauer for chiming in! Executive summary: this directives enables use of single-precision SSE floating point instruction by the compiler, and brings their performance in line with expectations, making Delphi XE2 64bit compiler the new King of the Delphi Hill. Let’s hope that this directive will in time face the same fate as $STRINGCHECKS did (ie. become another scary story for the long winter nights).
