decimalbased

Decimal-based refers to systems or methods that use base-10 numeral representation. In a decimal-based system, numbers are expressed using ten digits, 0 through 9, with place value determined by powers of ten. The same digits and the ten-digit base form the common framework for counting, measurement, and arithmetic in most everyday contexts.

The decimal system is widely considered to be a decimal-based adaptation of the Hindu-Arabic numeral system, which developed in India and was transmitted to the Western world through Arabic scholars. The key features are place-value notation and the concept of zero as a number, enabling compact representation of large numbers and consistent rules for addition, subtraction, multiplication, and division. By the late medieval period, decimal-based notation became standard in Europe and later spread worldwide.

In modern practice, decimal-based representations are used in education, finance, commerce, and everyday measurement. Calculations may be performed in decimal either by hand or with software and calculators. In computing, most hardware is binary-based, but decimal-based arithmetic is used for user-facing tasks and financial calculations through decimal floating-point formats or decimal fixed-point representations to preserve exactness and avoid rounding errors.

Decimal-based systems contrast with other bases, such as binary (base-2) and hexadecimal (base-16). The decimal system is generally considered more intuitive for humans, especially for arithmetic with common units, but base-2 efficiency is favored in computer hardware. Decimal-based approaches also include decimal fractions and fixed-point arithmetic used in financial reporting and accounting.
