Floating-point arithmetic is considered an esoteric subject by many people. This is rather surprising because floating-point is ubiquitous in computer systems. Almost every language has a floating-point datatype; computers from PCs to supercomputers have floating-point accelerators; most compilers will be called upon to compile floating-point algorithms from time to time; and virtually every op...

5.9 million children under age five died in 2015, 16 000 every day. Globally, under-five mortality rate has decreased by 53%, from an estimated rate of 91 deaths per 1000 live births in 1990 to 43 deaths per 1000 live births in 2015. The average annual rate of reduction in under-five mortality has accelerated from 1.8%  a year over the period 1990–2000 to 3.9%  for 2000–2015 , but remains insuf...

The sentence Every horse did not jump over the fence can be interpreted with the negation taking scope over the quantifier (i.e. not every horse jumped) or with the quantifier Every taking scope over the negation (ultimately providing the reading no horse jumped). Beginning with Musolino, Crain and Thornton (2000), much work has shown that while adults typically adopt a Not every reading in '2-...
