The mathematical operator U+2299 ⊙ CIRCLED DOT OPERATOR represents the XNOR gate or the Hadamard product , the element wise multiplication of matrices of same size denoted by A ⊙ B {\displaystyle A\odot B}
For the similar-looking operator named parallel, see ∥. Floor function : if x is a real number, ⌊ x ⌋ {\displaystyle \lfloor x\rfloor } is the greatest integer that is not greater than x . Ceiling function : if x is a real number, ⌈ x ⌉ {\displaystyle \lceil x\rceil } is the lowest integer that is not lesser than x .
In logic, a set of symbols is commonly used to express logical representation. The following table lists many common symbols, together with their name, how they should be read out loud, and the related field of mathematics.

Vertical alignment with the surrounding text can also be a problem; a work-around is described in the "Alignment with normal text flow" section below. The CSS selector of the images is img.tex. Apart from function and operator names, as is customary in mathematics, variables and letters are in italics; digits are not.
Mathematical operators and symbols are in multiple Unicode blocks. Some of these blocks are dedicated to, or primarily contain, mathematical characters while others are a mix of mathematical and non-mathematical characters. This article covers all Unicode characters with a derived property of "Math". [2] [3]
