System requirements:

• Intel or AMD processor
• Microsoft Windows operating system (tested on Windows 98/ME/2000/XP/Vista/7)
• 64-bit version runs only on 64-bit Windows

Installation:

1. Extract ALL files from the ZIP archive. I've created ZIP files by 7-zip, but you can use any archiver to extract files. Some archivers allow to double-click EXE file inside the archive and run it from a temporary folder, but that will NOT work.
2. Drag & drop the EXE file to the Start button which is in the bottom left screen corner.
3. Right-click the EXE file and choose Create shortcut. Then move this shortcut to the desktop.

Why to use 64-bit version:

• Fractions can have larger numerator and denominator. For example, expression (123456 * 12345678 / 3087105371) returns 493.714285714 in Precise Calculator 32-bit, but it returns 3456 / 7 in Precise Calculator 64-bit.
• Precise Calculator 32-bit cannot display numbers greater than 4E+20686623764, but Precise Calculator 64-bit maximum is 1E+9223372036854774730
• 64-bit version is much faster if you need precision greater than 1000 digits
