Calculator

Calculator is a clean, versatile, and easy-to-use calculator application that provides a wide range of calculation modes suitable for everyday arithmetic as well as advanced scientific, financial, and programming tasks. Within the Active@ LiveCD environment, it serves as a convenient tool for performing quick calculations during disk management, data recovery, and system administration operations, such as converting file sizes, calculating storage capacities, or working with hexadecimal values.

The application offers four distinct operating modes. Basic mode provides a simple interface for standard arithmetic operations, accessible to users of all experience levels. Advanced mode expands the available functionality with a comprehensive set of scientific and mathematical functions, including trigonometric, logarithmic, and exponential calculations, powers, factorials, and mathematical constants. Financial mode provides tools for common financial calculations such as compound interest, present and future value, and periodic payment amounts.

Programming mode is particularly relevant within the Active@ LiveCD environment, providing tools for working with numerical values in hexadecimal, decimal, octal, and binary number systems. It supports bitwise logical operations such as AND, OR, XOR, and NOT, and allows instant conversion between number bases — making it an invaluable companion when working with Active@ Disk Editor or other low-level disk analysis tools. A built-in calculation history panel records all previous calculations performed during the current session, allowing you to review and reuse earlier results without recalculation.
