On the constant in the Mertens product for arithmetic progressions. II. Numerical values
, 2007 We give explicit numerical values with 100 decimal digits for the constant in the Mertens product over primes in the arithmetic progressions $a \bmod q$, for $q \in \{3$, ..., $100\}$ and $(a, q) = 1$.Comment: The complete set of results can be ...

Tipología de los errores en el cálculo mental : un estudio en el contexto educativo [PDF]
, 1995 The present paper deals with a typology of errors and difficulty of Spanish students in a Teacher Training College when they apply historical mental computation methods (methods taken from the written tradition found in arithmetic textbooks) to solve ...

Error Analysis of Band Matrix Method [PDF]
, 1984 Numerical error in the solution of the band matrix method based on the elimination method in single precision is investigated theoretically and experimentally, and the behaviour of the truncation error and the roundoff error is clarified.

Converting an Integer to a Decimal String in Under Two Nanoseconds
Software: Practice and Experience, EarlyView.ABSTRACT Objective Converting binary integers to variable‐length decimal strings is a fundamental operation in computing. Conventional fast approaches rely on recursive division and small lookup tables. The goal of this work is to develop a significantly faster method for this task.

The evolution of binary system from predynastic Egypt to Leibniz era [PDF]
Journal of Mahani Mathematical ResearchEgyptians of the predynastic era had a good decimal number system for counting and addition. Although, up to some times, they had problem in counting beyond a million, by the dawn of their history, Narmer, the founder of the first Egyptian dynasty had ...

Issues with rounding in the GCC implementation of the ISO 18037:2008 standard fixed-point arithmetic
, 2020 We describe various issues caused by the lack of round-to-nearest mode in the \textit{gcc} compiler implementation of the fixed-point arithmetic data types and operations.

Caution Ahead: Numerical Reasoning and Look‐Ahead Bias in AI Models
Journal of Accounting Research, EarlyView.ABSTRACT Recent work within accounting and finance has highlighted that modern AI systems exhibit superhuman performance on a variety of foundational activities within these fields. However, the literature often does not provide economic rationale for why AI models seem to outperform, largely because these models are a black box.

Hardware Implementation of Densely Packed Decimal Encoding [PDF]
, 2010 Binary Coded Decimal ( BCD ) in which four bits are used for each decimal digit is a widely used encoding for decimal data .Decimal arithmetic and shifting are simplified by using operands in this form, and both rounding to a specified number of digits ...

Journal of Agricultural Economics, EarlyView.ABSTRACT We investigate the impact of air quality regulations targeting fine particulate matter (PM2.5) on farmland values in corn and soybean producing counties in the United States over the period 1997–2022. Using self‐reported farmland value data from the Agricultural Census and county‐level pollution classifications provided by the Environmental ...

British Journal of Developmental Psychology, EarlyView.Abstract The ability to read and write multi‐digit numbers is increasingly recognised as a critical component of mathematical literacy. Previous studies showed that this skill takes years to develop, and children are not fluent even by the fourth grade. Here, we examined fifth‐grade children as they read aloud briefly presented digit strings. They were
