![]() For this purpose, the size and precision of Extended type is reduced: TYPE Correspondingly, if there are only 64-bit versions of the DLL on your computer, you won't be able to use all functions at design-time and, vice versa, if you have only 32-bit versions of the DLLs, your application won't be able to work at run-time.įor this type in a 64-bit applications compiler generates SSE2 instructions instead of FPU, and that greatly improves performance in applications that use this type a lot (where data accuracy is needed). ![]() In this case, you will have to separate your package into two packages, one of which will be used as run-time only, and the other as design-time only.įor the same reason, if your design-time packages require that certain DLLs be loaded, you should remember that design-time packages can be only 32-bit and that is why they can load only 32-bit versions of these DLLs, while at run-time 64-bit versions of the DLLs will be loaded. This might be a source of difficulties if your package is simultaneously both a run-time and a design-time package, as it is more than likely that this package won't be compiled for the 64-bit platform. Therefore, if you develop your own components, you should remember that for the purpose of developing components with the 64-bit platform support, you have to compile run-time packages both for the 32- and 64-bit platforms, while design-time packages need to be compiled only for the 32-bit platform. So, all design-time packages in RAD Studio XE2 IDE RAD Studio XE2 IDE is a 32-bit application. Live data bindings with visual components Ĭhanges in 64-bit Application DevelopmentĦ4-bit platform support implies several important changes that each developer must keep in mind prior to the development of a new application or the modernization of an old one. ![]() FireMonkey application development platform.Moreover, you can create visually spectacular applications with the help of the FireMonkey GPU application platform. Additionally, it is now possible to create 64-bit Windows applications to fully benefit from the power of new hardware. It allows deploying your applications both on Windows and Mac OS platforms. ![]() RAD Studio XE2 is the major breakthrough in the line of all Delphi versions of this product. ![]()
