- The Yakima River is a tributary of the Columbia River in south central and eastern Washington state, named for the indigenous Yakama people. Lewis and Clark mention in their journals that the Chin-nâm pam (or the Lower Snake River Chamnapam Nation) called the river Tâpe têtt (also rendered Tapteete), possibly from the French tape-tête, meaning “head hit”. The length of the river from headwaters to mouth is 214 miles (344 km), with an average drop of 9.85 feet per mile (1.866 m/km). It is the longest river entirely in Washington state.

Floating-point numbers are very useful for scientific programming, but early microprocessors only supported integers directly. Although floating-point was common in mainframes back in the 1950s and 1960s, it wasn’t until 1980 that Intel introduced the 8087 floating-point coprocessor for microcomputers. Adding this chip to a microcomputer such as the IBM PC made floating-point operations up to 100 times faster. This was a huge benefit for applications such as AutoCAD, spreadsheets, or flight simulators. The downside was the 8087 chip cost hundreds of dollars.
