Given the popularity of decimal arithmetic, hardware implementation of decimal operations has been a hot topic of research in recent decades. Besides the four basic operations, the square root can be implemented as an instruction directly in the hardware, which improves the performance of the decimal floating-point unit in the processors. Hardware implementation of decimal square rooters is usu...

Commercial applications and databases typically store numerical data in decimal format. Currently, however, microprocessors do not provide instructions or hardware support for decimal floating-point arithmetic [ 1 ]. Consequently, decimal numbers are often read into computers, converted to binary numbers, and then processed using binary floating-point arithmetic. Results are then converted back...

Financial and commercial data are mostly represented in decimal format. To avoid errors introduced when converting some fractions to binary, these processed with arithmetic. Most processors only have hardwired binary arithmetic units. So, operations executed slow software-based functions. For the fast execution of operations, dedicated hardware units been proposed designed FPGA. Decimal multipl...

Decimal fractions comply with the base-10 notational system of natural Arabic numbers. Nevertheless, recent research suggested that decimal fractions may be represented differently than natural numbers because two number processing effects (i.e., semantic interference and compatibility effects) differed in their size between decimal fractions and natural numbers. In the present study, we examin...

Precision and rounding—decimal places and significant digits Reporting of numerical data is an important element in medical research. Summary statistics are often reported to too many decimal places, leading to spurious precision and over-complicated presentation1; less often, too few decimal places are used, resulting in a lack of precision. Surprisingly, few guidelines on the subject exist. T...

A decimal sequence is obtained when a number is represented in a decimal form in a base r and it may terminate, repeat or be aperiodic. For a certain class of decimal sequences of q 1 , prime, the digits spaced half a period apart add up to q 1 − r , where r is the base in which the sequence is expressed. Decimal sequences are known to have good crossand auto-correlation properties and they can...
