Googol + 2.4 (now Free)
We released version 2.4 of Googol+, now as Freeeware. As previously, it installs from the same setup program either as 32-bit or 64-bit, depending on your operating system. In the previous release, the 32-bit version might hang in factorizations. This has been fixed.
Googol+ is the only Windows Arbitrary Precision Calculator that does not run from a command line, so its use offers great convenience and user experience. Download it, if you enjoy maths!
