Hexadecimal (also known as base-16 or simply hex) is a positional numeral system that represents numbers using a radix (base) of sixteen. Unlike the decimal system representing numbers using ten symbols, hexadecimal uses sixteen distinct symbols, most often the symbols "0"–"9" to represent values 0 to 9 and "A"–"F" to represent values from ten to fifteen.
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.
A binary clock might use LEDs to express binary values. In this clock, each column of LEDs shows a binary-coded decimal numeral of the traditional sexagesimal time.. The common names are derived somewhat arbitrarily from a mix of Latin and Greek, in some cases including roots from both languages within a single name. [27]
Two's complement is the most common method of representing signed (positive, negative, and zero) integers on computers, [1] and more generally, fixed point binary values. Two's complement uses the binary digit with the greatest value as the sign to indicate whether the binary number is positive or negative; when the most significant bit is 1 the number is signed as negative and when the most ...
Invert all the bits through the number. This computes the same result as subtracting from negative one. Add one; Example: for +2, which is 00000010 in binary (the ~ character is the C bitwise NOT operator, so ~X means "invert all the bits in X"): ~00000010 → 11111101; 11111101 + 1 → 11111110 (−2 in two's complement)

The original firmware still had a bug where numbers whose hexadecimal representation ends in E or F are displayed incorrectly in decimal mode, which was fixed by a community effort in October 2023. Several emulators , including official by HP, are available for desktop computers, web browsers, smartphones and other calculators.
Here is another example for saturating subtraction when the valid range is from 0 to 100 instead: 30 - 60 → 0. (not the expected -30.) As can be seen from these examples, familiar properties like associativity and distributivity may fail in saturation arithmetic.
