Deprecated Symbols of Number Theory
This page contains symbols which may or may not be in current use, but are either non-standard in mathematics or have been superseded by their more modern variants.
On $\mathsf{Pr} \infty \mathsf{fWiki}$ the intention is to present a consistent style, and so these symbols are to be considered deprecated.
Divisor
- $x \mid y$
This means $x$ is a divisor of $y$.
The symbol $\mid$ has been (or is in the process of being) superseded by $\divides$, which is becoming increasingly popular since many mathematicians are of the opinion that $\mid$ is overused, and hence a possible cause for confusion.
The $\LaTeX$ code for \(\mid\) is \mid
.
Integer Part
- $\sqbrk x$
For $x \in \R$, the greatest integer less than or equal to $x$.
That is, it is the integer part of a given real number.
$\sqbrk x$ has been (or is in the process of being) superseded by $\floor x$, due to the already widespread uses of square brackets.
The $\LaTeX$ code for \(\sqbrk x\) is \sqbrk x
