The Use of Round Numbers

Journal of Professional Issues in Engineering, 1983
Round numbers are widely used in engineering. Through a process of tacit co‐ordination between the writer and the reader, round numbers help focus attention simply by being round, facilitate agreement, speed review processes, and reduce argument.

The roundness-measure of a natural number

2021
\textit{S. Ramanujan} [Proc. Lond. Math. Soc. (2) 14, 347--409 (1915; JFM 45.1248.01)] introduced superior highly composite number (s.h.c.). In general it is difficult to test whether a given number \(n\) is s.h.c. The purpose of the paper under review is to devise one such criterion and the author is successful in doing so by introducing the ...

Rounding of Polytopes in the Real Number Model of Computation

Mathematics of Operations Research, 1996
Let 𝒜 be a set of m points in ℝn. We show that the problem of (1 + ϵ)n-rounding of 𝒜, i.e., the problem of computing an ellipsoid E ⊆ ℝn such that [(1 + ϵ)n]−1E ⊆ conv. hull(𝒜) ⊆ E, can be solved in O(mn2(ϵ−1 + ln n + ln ln m)) arithmetic operations and comparisons.

Round Numbers as Goals

Psychological Science, 2010
Where do people’s reference points come from? We conjectured that round numbers in performance scales act as reference points and that individuals exert effort to perform just above rather than just below such numbers. In Study 1, we found that professional baseball players modify their behavior as the season is about to end, seeking to finish with a ...

Round numbers revisited. A new fuzzy approach

Fuzzy Sets and Systems, 2007
A round number was defined by Hardy and Ramanujan as being one that has a considerable number of comparatively small prime factors. This description contains words such as `considerable' and `comparatively small' that have vague meaning. This paper deals with fuzzy models for grasping the imprecision attached to these words.

A new system for rounding numbers

Journal of Chemical Education, 1991
The conventional rules for rounding numbers after calculations are inadequate. They do not consider the significance of the digits dropped, and they lead to inequitable treatment of numbers rounded up relative to numbers truncated.

Errors in Computations and the Rounded Number

The Mathematics Teacher, 1922
I believe it is now quite generally felt among teachers of mathematics that it is their duty to give the boy and girl such mathematical instruction as may he of use to them in their daily life after leaving the high school. This feeling has given rise to some of the modern ideas as to what should be taught the boy and girl who does not go beyond the ...

Generalized Fibonacci Numbers are Rounded Powers

1990
We show that the k th degree generalized Fibonacci number of order n ≥ 0,F n (k) can be computed by $$\begin{array}{l} F_n^{\left( k \right)} = ROUND\left\{ {\alpha _0^{\left( k \right)}{{\left( {\Phi _0^{\left( k \right)}} \right)}^n}} \right\}\\ = \left\lfloor {\frac{{\Phi _0^{\left( k \right)} - 1}}{{(k + 1)\Phi _0^{\left( k \right)} - 2k ...
