If the modulus is the absolute value of a fundamental discriminant there is a real primitive character (there are two if the modulus is a multiple of 8); otherwise if there are any primitive characters [35] they are imaginary. [43]
Some languages such as Julia include a true 32-bit Unicode character type as primitive. [24] Other languages such as JavaScript, Python, Ruby, and many dialects of BASIC do not have a primitive character type but instead add strings as a primitive data type, typically using the UTF-8 encoding. Strings with a length of one are normally used to ...
In particular, primitive real Dirichlet characters are in a 1–1 correspondence with quadratic fields = (), where is a nonzero square-free integer (we can include the case () = to represent the principal character, even though it is not a quadratic field).
A string of seven characters. In computing and telecommunications, a character is a unit of information that roughly corresponds to a grapheme, grapheme-like unit, or symbol, such as in an alphabet or syllabary in the written form of a natural language. [1] Examples of characters include letters, numerical digits, common punctuation marks
The formula shows that the L-function of χ is equal to the L-function of the primitive character which induces χ, multiplied by only a finite number of factors. [ 6 ] As a special case, the L -function of the principal character χ 0 {\displaystyle \chi _{0}} modulo q can be expressed in terms of the Riemann zeta function : [ 7 ] [ 8 ]
The nnnn or hhhh may be any number of digits and may include leading zeros. The hhhh may mix uppercase and lowercase, though uppercase is the usual style. In contrast, a character entity reference refers to a character by the name of an entity which has the desired character as its replacement text.
Primitive data types or built-in data types are types that are built-in to a language implementation. User-defined data types are non-primitive types. For example, Java's numeric types are primitive, while classes are user-defined. A value of an atomic type is a single data item that cannot be broken into component parts.
Hu Qiaomu said: [18] "The (primitive) components of Chinese characters should be reduced, and the components of Chinese characters should be made independent characters as many as possible; those that cannot be characters should be universal and easy to say. This may be more important than reducing the number of strokes and characters.
