How can gcc/mingw-64 build x64 executables with double precision set to
80 bits?
You'll need to define __USE_MINGW_ANSI_STDIO to 1 at the beginning.
/***************************/
#define __USE_MINGW_ANSI_STDIO 1
#include <stdio.h>
int main(void) {
long double x = 1.18L;
printf("%La\n%.18Lg\n", x, x);
return 0;
}
/***************************/
Outputs (with both 32-bit and 64-bit mingw builds of gcc):
0x9.70a3d70a3d70a3dp-3
1.18
You can, of course, build with -D__USE_MINGW_ANSI_STDIO on the command line
if you don't want to define the symbol in the script.
Cheers,
Rob
