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

$\begingroup$ @richard1941 - You appear to have completely missed the point of my remark, which was to give an example of why "rounding to the nearest integer" is ambiguous, thus supporting the point that when discussing rounding, one should be clear about what rules you are following

so clearly the floor of x divided by x must be less then or equal to 2 3; or x divided by the floor of x is greater then or equal to 3 2; Of course there is another constraint that I have left out (3⌊x⌋ ≤ 2x < 3⌊x⌋+1) but I am sure it is simpler this way

$\begingroup$ I think "simply" isn't quite the right word, maybe "effectively " IEEE 754 format (in normal form) stores numbers as $\pm 1 bbb bb \times 2^n$, so to compute the floor it would first need to figure out where the decimal place is, and then replaces the corresponding digits (if any) to 0, and if the result would be 0, then the format switches to denormalized form
- How do the floor and ceiling functions work on negative numbers?
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 OR Floor always rounding towards zero Ceiling always rounding away from zero E g floor(x)=-floor(-x) if x<0, floor(x) otherwise

\floor is not defined in amsmath The \DeclaredPairedDelimiter' is good, but in comparison to the \newcommand` above it mostly provides an easy way to change the code when a different size is required
- How to represent the floor function using mathematical notation?
When a computer evaluates floor(x), it's all math The printed (or electronically stored) notation for a rational number which approximates a real number is a mathematical object The printed (or electronically stored) notation for a rational number which approximates a real number is a mathematical object

I like the combined floor ceiling symbol for nearest integer, although Wolfram calls it "cumbersome" and "not recommended" When I was at school, if you wanted to show an answer was rounded to the nearest 10th, you'd put "(to 1dp)" after it, where "dp" stands for "decimal place"
