A quirk of binary floating-point is that x l will actually fit into s-1 bits (the sign bit of x l is used as an additional bit). For binary64 (p=53), using s=27 means that both halves of the number will fit into 26 bits. (x h ...

WebThis is very, very wrong. long double is generally not 128-bits, and is often an 80-bit extended-precision float (most notably on x86, which is a very important platform). VIsual C++ on x86 makes this just a synonym for double.

So, given a type T, the number of bits in an object of type T is: #include size_t nbits = sizeof (T) * CHAR_BIT. Note that, except for unsigned char type, all possible combinations of nbits bits above may not represent a valid value of type T.
