- How to write ceil and floor in latex? - LaTeX Stack Exchange
\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 does a floor function work? - Mathematics Stack Exchange
$\begingroup$ 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
- discrete mathematics - Solving equations involving the floor function . . .
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
- 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
- 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
- Floor function of a product - Mathematics Stack Exchange
By definition of floor, $\lfloor xy\rfloor$ must be the greatest such integer Thus, we have $$\lfloor xy\rfloor \ge \lfloor x\rfloor\lfloor y\rfloor,$$ giving us the left inequality
