Packed decimal specifies a method of encoding decimal numbers by using each byte to represent two decimal digits. Packed decimal representation stores decimal data with exact precision. The fractional ...

Editor's Note: This is the first article in a two-part series on decimal representations and decimal arithmetic in general, and on Binary Coded Decimal (BCD) in particular. In this first installment, ...

On π-day, one mathematician explores our fascination with pi and asks why we obsessively compute its digits. Pi Day, the International Day of Mathematics, is celebrated on 14 March, due to the date's ...

Pi is, quite possibly, the most famous number known to man.* This fact is a little bit ironic, as we don't actually have a number for pi. Well, not a complete number anyways, because pi never ends. If ...

Mathematics students often encounter confusion when distinguishing between rational and irrational numbers. However, mastering this fundamental concept becomes straightforward once you understand the ...

Not all Java developers need the precision that BigDecimal offers. However, those who do usually don’t have to use BigDecimal for very long before running into the java.lang.ArithmeticException with ...

In the first column of this series, I introduced the concepts underlying BCD (binary-coded-decimal) representations. In my second column I discussed how we go about adding and subtracting unsigned BCD ...

Pi Day, the International Day of Mathematics, is celebrated on 14 March, due to the date's American shorthand 3/14 – the first three digits of π. The true number of digits after the decimal place ...
