Compare with Definitions

Decimal

The decimal numeral system (also called the base-ten positional numeral system, and occasionally called denary or decanary) is the standard system for denoting integer and non-integer numbers. It is the extension to non-integer numbers of the Hindu–Arabic numeral system.

Hexadecimal

In mathematics and computing, the hexadecimal (also base 16 or hex) numeral system is a positional numeral system that represents numbers using a radix (base) of 16. Unlike the decimal system representing numbers using 10 symbols, hexadecimal uses 16 distinct symbols, most often the symbols "0"–"9" to represent values 0 to 9, and "A"–"F" (or alternatively "a"–"f") to represent values from 10 to 15.

Decimal

A linear array of digits that contains a single period, called the decimal point, is possibly preceded by a minus sign (-), and represents a real number, with each successive digit to the right of the decimal point indicating a multiple of the next negative power of 10, and each successive digit to the left of the decimal point indicating a multiple of the next non-negative power of ten, beginning with 100 = 1. For example, 245.3 represents the real number (2 × 102) + (4 × 101) + (5 × 100) + (3 × 10-1) = 200 + 40 + 5 + 3/10 , and -1.04 represents the real number (-1 × 100) + (-4 × 10-2). Also called mixed decimal.

Hexadecimal

Of, relating to, or based on the number 16
The hexadecimal number system.

Decimal

Such an array of digits in which there are no nonzero digits to the left of the decimal point, representing a real number between -1 and 1. Also called decimal fraction.
