Die analysis of the 8087 math coprocessor’s fast bit shifter (righto.com)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.

Elvis Presley (Wikipedia)Elvis Aaron Presley (January 8, 1935 – August 16, 1977), commonly referred to by his first name, Elvis, was an American singer and actor. Known as the “King of Rock and Roll”, he is regarded as one of the most significant cultural figures of the 20th century. Presley’s energized interpretations of songs and sexually provocative performance style, combined with a singularly potent mix of influences across color lines during a transformative era in race relations, brought both great success and initial controversy.
