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 … WebFeb 16, 2012 · long double is not required to provide more precision than double.However, even if it does, you have to tell the compiler that the literal is a long double.Without a decimal point, the compiler will assume 9223372036854775807 is some kind of integer.

Web5 Answers. The letters 100000000000 make up a literal integer constant, but the value is too large for the type int. You need to use a suffix to change the type of the literal, i.e. The suffix LL makes the literal into type long long. C is not "smart" enough to conclude this from the type on the left, the type is a property of the literal ... WebWith the GNU C Compiler, long double is 80-bit extended precision on x86 processors regardless of the physical storage used for the type (which can be either 96 or 128 bits), On some other architectures, long double can be double-double (e.g. on PowerPC) or 128-bit quadruple precision (e.g. on SPARC).
