Calculator is an application for mathematical operations that was first introduced with Windows 1.0.

History[edit | edit source]

Calculator was already included in the very first builds of Windows 1.0. In Windows 3.0, the program was completely re-written, adding a Scientific mode allowing for more complex operations such as sin or log. The Calculator remained unchanged in terms of functionality and appearance until Windows Vista, save for its portation to 32-bit and later 64-bit and some reorganizations of buttons. In Windows 7, the Calculator app got redesigned and the program received features like History, Programmer Mode, Statistics Mode, Date Calculation and Unit Conversion. In Windows 8.1, a Metro-based version was introduced, evolving into a version based on UWP in Windows 10. Consequently, the original Calculator was removed, save for its LTSC variant. In Windows 10 build 16226, a currency converter was introduced. The UWP version of Calculator was made open-source in 2019 and its source code was made available on GitHub.[1] In Windows 11 build 22000.132, a WinUI 2.7 version was introduced. This would be backported to recent versions of Windows 10 via Microsoft Store in late 2022.
