A decimal system (also called base-ten, denary or decenary) is a numeral system that uses ten as its radix (base). Decimal systems are the global standard for denoting integer and non-integer numbers. The way of denoting numbers in a decimal system is often referred to as decimal notation. Presently, the most common decimal system is the Hindu–Arabic numeral system, which is a positional numeral system. However, there are also non-positional base-ten systems, such as Roman or Chinese numerals. A decimal numeral (also often just decimal or, less correctly, decimal number), generally refers to the notation of a number in a decimal numeral system. Non-integral decimals may be identified by a d…

ON THE TRANSFINITE LENGTH OF THE SEQUENCE OF DIGITS IN THE EXPANSION OF A TRANSCENDENTAL NUMBER AFTER THE DECIMAL POINT. We prove that (if we assume as consistent Cantor's diagonal process) among the transcendental numbers there are different transfinite cardinalities in the total of digits that compose them in their expansion after the decimal point. Some transcendental can be made up of a total of digits ℵ0 after the decimal point, while another by ℵ1 or ℵ2, or ℵ𝛂 figures. So, we proceed to mathematically construct such cardinalities. Which in turn forces us to also deduce the existence, within the class R of the real numbers, of Rα infinite subsets of these numbers with ℵα cardinalities…

A fraction (from Latin: fractus, "broken") represents a part of a whole or, more generally, any number of equal parts. When spoken in everyday English, a fraction describes how many parts of a certain size there are, for example, one-half, eight-fifths, three-quarters. A simple fraction (examples: ⁠1/2⁠ and ⁠17/3⁠) consists of an integer numerator, displayed above a line (or before a slash like 1⁄2), and a non-zero integer denominator, displayed below (or after) that line. If these integers are positive, then the numerator represents a number of equal parts, and the denominator indicates how many of those parts make up a unit or a whole. For example, in the fraction ⁠3/4⁠, the numerator 3 i…

Positional notation, also known as place-value notation, is the property of a numeral system that the value represented by each symbol in a written numeral depends not only on its appearance but also on its position. Each symbol fits in a specific place or position, representing a power of a fixed base. The most common numeral system used today, the Hindu–Arabic numeral system, is a positional system in base ten; each of ten numerical digits is a distinct symbol representing one of the numbers zero through nine, and in the context of the full numeral, each symbol's value is the digit multiplied by a power of ten. Most early numeral systems, such as Roman numerals, are essentially based on t…
