Jun 8, 2013 · Is there a macro in latex to write ceil(x) and floor(x) in short form? The long form \\left \\lceil{x}\\right \\rceil is a bit lengthy to type every time it is used.

Is there a convenient way to typeset the floor or ceiling of a number, without needing to separately code the left and right parts? For example, is there some way to do $\\ceil{x}$ instead of $\\lce...

The correct answer is it depends how you define floor and ceil. You could define as shown here the more common way with always rounding downward or upward on the number line.

Aug 18, 2017 · I understand what a floor function does, and got a few explanations here, but none of them had a explanation, which is what i'm after. Can someone explain to me what is going on behind the scenes ...

Jun 4, 2018 · The most natural way to specify the usual principal branch of the arctangent function basically uses the idea of the floor function anyway, so your formula "for" the floor function is correct but somewhat circular.

17 There are some threads here, in which it is explained how to use \lceil \rceil \lfloor \rfloor. But generally, in math, there is a sign that looks like a combination of ceil and floor, which means round, aka nearest integer. Is there a way to draw this sign in Latex's math mode?

The floor function turns continuous integration problems in to discrete problems, meaning that while you are still "looking for the area under a curve" all of the curves become rectangles.

It natively accepts fractions such as 1000/333 as input, and scientific notation such as 1.234e2; if you need even more general input involving infix operations, there is the floor function provided by package xintexpr.

The floor function (also known as the entier function) is defined as having its value the largest integer which does not exceed its argument. When applied to any positive argument it represents the integer part of the argument obtained by suppressing the fractional part.
