WebIf you are using MinGW, the problem is that by default, MinGW uses the I/O resp. formatting functions from the Microsoft C runtime, which doesn't support 80 bit floating point numbers (long double == double in Microsoft land).However, MinGW also comes with a set of alternative implementations that do properly support long doubles. To use them, prefix … WebDev-c++ uses MinGW, which uses the gcc compiler and the Microsoft runtime library.

"WebJan 19, 2010 · The number of bits in a byte is CHAR_BIT, which usually is 8, but can be different. 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. " - Bits/long-double.h
