How Java's Floating-Point Hurts Everyone Everywhere
Short summary:
will not deter clever folks from writing Java programs that depend. most programs behave, no law limits every program's output using programs written in those languages. Among their programs are
many that predate IEEE Standard 754 ...
Long summary:
These numerical experts, engineers, scientists, statisticians, â ¦ are used to programming in C,
Fortran, Ada, â ¦ or to using programs written in those languages. Among their programs are
many that predate IEEE Standard 754 (1985) for Binary Floating-Point Arithmetic; these
programs, many written to be â Portableâ to the computers of the 1970s, demand no more from
floating-point than Java provides, so their translation into Java is almost mechanical. the folks out there are completely clueless about floating-point.â ( J.G., 28 Feb. 1998 )
Their numerical inexpertise will not deter clever folks from writing Java programs that depend
upon floating-point arithmetic to perform parts of their computations:
â ¢ Materials lists and blueprints for roofing, carpentry, plumbing, wiring, painting.
â ¢ Numerically controlled machine tools and roboticized manufacturing, farming and recycling.
â ¢ Customizable designs for home-built furniture, sailboats, light aircraft, go-karts, irrigation.
â ¢ Navigation for sailboats, light aircraft and spaceships while their pilots doze at the wheel.
â ¢ Economic and financial forecasts, estimated yield on investments, and portfolio management.
â ¢ Predictions of supply and demand, predictive inventory management, just-in-time delivery
