Calendar of Romulus The only calendar with a ten month year was the Roman calendar calendar of Romulus adopted sometime after Romulus and Remus founded the city of Rome in 753 BC, when Romulus killed Remus. According to Roman writers, including Censorinus and Macrobius , it had ten of the twelve months in our modern calendar, March through December, but it only had 304 days in its year. The remaining days needed to form a solar year were winter days not assigned to any month. It only lasted until about 700 BC when King Numa Pompilius Numa , the successor of Romulus, added the winter months of January and February and rearranged the number of days in each month, creating the Roman calendar . Egyptian, Alexandrian, Coptic, and Ethiopian calendars The Egyptian calendar of the first three millennia BC had twelve months of 30 days each, consisting of three ten day weeks, plus five epagomenal days at the end of the year.

Some programming languages provide a built in primitive or library decimal data type to represent non repeating decimal fraction s like 0.3 and 1.17 without rounding, and to do arithmetic on them. Examples are the code decimal.Decimal code type of Python programming language Python , and analogous types provided by other languages. Rationale Fractional numbers are supported on most programming languages as floating point number s or fixed point number s. However, such representations typically restrict the denominator to a power of two. Most decimal fractions or most fractions in general cannot be represented exactly as a fraction with a denominator that is a power of two. For example, the simple decimal fraction 0.3 3 10 might be represented as 5404319552844595 18014398509481984 0.299999999999999988897769... . This inexactness causes many problems that are familiar to experienced programmers. For example, the expression code 0.1 7 0.7 code might counterintuitively evaluate to false in some systems, due to the inexactness of the representation of decimals. Although all decimal fractions are fraction s, and thus it is possible to use a rational data type to represent it exactly, it may be more convenient in many situations to consider only non repeating decimal fractions fractions whose denominator is a power of ten . For example, fractional units of currency worldwide are mostly based on a denominator that is a power of ten. Also, most fractional measurements in science are reported as decimal fractions, as opposed to fractions with any other system of denominators. A decimal data type could be implemented as either a floating point number or as a fixed point number . In the fixed point case, the denominator would be set to a fixed power of ten.

The term complex representation has slightly different meanings in mathematics and physics. In mathematics , a complex representation is a group representation of a group or Lie algebra on a complex vector space. In physics , a complex representation is a group representation of a group or Lie algebra on a complex vector space that is neither real representation real nor pseudoreal representation pseudoreal . In other words, the Group mathematics group elements are expressed as complex matrices, and the complex conjugate of a complex representation is a different, non equivalent representation. For compact groups, the Frobenius Schur indicator can be used to tell whether a representation is real, complex, or pseudo real. For example, the N dimensional fundamental representation of SU N for N greater than two is a complex representation whose complex conjugate is often called the antifundamental representation . algebra stub Category Representation theory of groups ... more details
