A3Calc is a calculator program, which is freely available for Win32 -platform (Commercial version for Nokia 92xx Communicators). The Communicator user can forget about ordinary business/scientific calculators and use A3Calc instead - no extra hardware needed!

A3Calc is developed to rapidly interpret BASIC applications in Symbian platform, which has only a fraction of resources comparing to desktop PCs. Because of tough requirements of Communicator, A3CalcТ‘s performance in PC-platform is unbeatable. A3Calc BASIC applications run just as well in both Windows and Symbian platforms.
