#include <float.h>
/* This is the default value loaded into the 80x87 control word.
If you want higher precision, then change PC_53 to PC_64. The
reason we have the default set to PC_53 is generate reproducible
floating-point results regardless of the level of optimization
chosen for the compiler.
This value is loaded when the 80x87 is initialized by the startup
code, and also when _fpreset is called.
