Decimal Floating Point
The System z9 was the first commercial server to add IEEE 754 decimal floating point instructions, although these instructions were implemented in microcode with some hardware assists. The System z10 implements the main IEEE 754 decimal floating point operations in a built-in, integral component of each processor core and instruction set architecture. As examples, Enterprise PL/I, XL C, and the z/OS Java BigDecimal class can exploit hardware decimal floating point.

Famous quotes containing the words decimal, floating and/or point:
“It makes little sense to spend a month teaching decimal fractions to fourth-grade pupils when they can be taught in a week, and better understood and retained, by sixth-grade students. Child-centeredness does not mean lack of rigor or standards; it does mean finding the best match between curricula and children’s developing interests and abilities.”
—David Elkind (20th century)
“I know, it must have been my imagination, but it makes me realize how desperately alone the Earth is. Hanging in space like a speck of food floating in the ocean. Sooner or later to be swallowed up by some creature floating by.... Time will tell, Dr. Mason. We can only wait and wonder. Wonder how, wonder when.”
—Tom Graeff. Young astronomer, Teenagers from Outer Space, after just seeing the invading spaceship through his telescope, and dismissing it (1959)
“There are neither good nor bad subjects. From the point of view of pure Art, you could almost establish it as an axiom that the subject is irrelevant, style itself being an absolute manner of seeing things.”
—Gustave Flaubert (1821–1880)
