Number of symbols Range of characters C1 controls: 32 control codes: U+0080 to U+009F Latin-1 punctuation and symbols: 32 punctuation and symbols: U+00A0 to U+00BF Letters: 30 pairs of majuscule and minuscule accented Latin characters: U+00C0 to U+00D6, U+00D8 to U+00F6 and U+00F8 to U+00FF Mathematical operators
The pre-increment and pre-decrement operators increment (or decrement) their operand by 1, and the value of the expression is the resulting incremented (or decremented) value. The post -increment and post -decrement operators increase (or decrease) the value of their operand by 1, but the value of the expression is the operand's value prior to ...
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 .
In mathematics, a unary operation is an operation with only one operand, i.e. a single input. [1] This is in contrast to binary operations, which use two operands. [2] An example is any function : , where A is a set; the function is a unary operation on A.
The Supplemental Mathematical Operators block (U+2A00–U+2AFF) contains various mathematical symbols, including N-ary operators, summations and integrals, intersections and unions, logical and relational operators, and subset/superset relations.
The operator precedence is a number (from high to low or vice versa) that defines which operator takes an operand that is surrounded by two operators of different precedence (or priority). Multiplication normally has higher precedence than addition, [ 1 ] for example, so 3+4×5 = 3+(4×5) ≠ (3+4)×5.

The following list includes the continued fractions of some constants and is sorted by their representations. Continued fractions with more than 20 known terms have been truncated, with an ellipsis to show that they continue. Rational numbers have two continued fractions; the version in this list is the shorter one.
