Comparing Floating-Point Numbers Is Tricky

Floating-point math is fraught with subtle gotchas, and comparing values properly is no exception. Here we discuss common pitfalls, examine some possible solutions, and try to beat Boost. Things you probably know about floats If you need to represent a non-integer in a mainstream programming language, you’ll probably end up using IEEE 754 floating-point values. Since their standardization in 1985,
