Windows Calculator is a software calculator developed by Microsoft and included in Windows. In its Windows 10 incarnation it has four modes: standard, scientific, programmer, and a graphing mode. The standard mode includes a number pad and buttons for performing arithmetic operations. The scientific mode takes this a step further and adds exponents and trigonometric functions, and programmer mode allows the user to perform operations related to computer programming. In 2020, a graphing mode was added to the Calculator, allowing users to graph equations on a coordinate plane.[3]
The Windows Calculator is one of a few applications that he been bundled in all versions of Windows, starting with Windows 1.0. Since then, the calculator has been upgraded with various capabilities.
In addition, the calculator has also been included with Windows Phone[4] and Xbox One.[citation needed] The Microsoft Store page proclaims HoloLens support as of February 2024, but the Calculator app is not installed on HoloLens by default.
History[edit]A simple arithmetic calculator was first included with Windows 1.0.[5]
In Windows 3.0, a scientific mode was added, which included exponents and roots, logarithms, factorial-based functions, trigonometry (supports radian, degree and gradians angles), base conversions (2, 8, 10, 16), logic operations, statistical functions such as single variable statistics and linear regression.
Windows 9x and Windows NT 4.0[edit]Until Windows 95, it uses an IEEE 754-1985 double-precision floating-point, and the highest representable number by the calculator is 21024, which is slightly above 10308 (≈1.80 × 10308).
In Windows 98 and later, it uses an arbitrary-precision arithmetic library, replacing the standard IEEE floating point library.[6] It offers bignum precision for basic operations (addition, subtraction, multiplication, division) and 32 digits of precision for advanced operations (square root, transcendental functions). The largest value that can be represented on the Windows Calculator is currently
