Hello, the comment system on your blog eats comments, that become lost forever when submitted. You might want to know that. Apart from that: 1) “2147483650f” is Java syntax. Also this number, written in C++ as 2147483650.0f, actually represents the number 2147483648 (assuming float is the single-precision IEEE 754 format). You might want to denote that number 2147483648.0f, which would be less confusing. 2) the line “const int min = 0x80000000;” does NOT contain undefined behavior. The overflows occurs during a conversion from an integer type to a signed integer type. Overflow during such a conversion is implementation-defined (or an implementation-defined signal is raised). Even an implementation-defined signal is not undefined behavior, but in practice, the compiler you use produces wrap-around behavior, and it will continue to do so, because it has been forced to document it.
