This study investigated whether new teaching resources and minimal support could help teachers make a difference to children's understanding of decimal numeration. Three schools were offered resources and a professional development session specifically to address the common misconceptions children have about decimal numbers. One school agreed to participate, and four teachers were supplied with...

Decimal multiplication is important in many commercial applications including financial analysis, banking, tax calculation, currency conversion, insurance, and accounting. This paper presents two novel designs for fixed-point decimal multiplication that utilize decimal carry-save addition to reduce the critical path delay. First, a multiplier that stores a reduced number of multiplicand multipl...

Decimal arithmetic is very important for computations in financial and commercial transactions which include banking system, tax calculation, billing etc. Decimal arithmetic algorithm mainly includes decimal addition and multiplication. The main problem in the existing decimal arithmetic is the need for correcting the result as it is in the binary form. This causes the implementation area to be...

OBJECTIVE To investigate approaches to supporting the analysis of historical medication datasets with RxNorm. METHODS We created two sets of National Drug Codes (NDCs). One is based on historical NDCs harvested from versions of RxNorm from 2007 to present. The other comprises all sources of NDCs in the current release of RxNorm, including proprietary sources. We evaluated these two resources ...

It was proved by Champernowne [2] that the decimal . 1234567891011 . . . is normal, and by Besicovitch [11 that the same holds for the decimal . 1491625 . . . . Copeland and Erdös [3] have proved that if p i, P2 . . . . is any sequence of positive integers such that, for every 0 < 1, the number of p's up to n exceeds nB if n is sufficiently large, then the infinite decimal •p ip 2p 3 . . . is n...
