Example:
    #include <stdio.h>
    #include <float.h>

    char *status[2] = { "No", "  " };

    void main()
      {
        unsigned int fp_status;

        fp_status = _status87();

        printf( "80x87 status\n" );
        printf( "%s invalid operation\n",
                status[ (fp_status & SW_INVALID) == 0 ] );
        printf( "%s denormalized operand\n",
                status[ (fp_status & SW_DENORMAL) == 0 ] );
        printf( "%s divide by zero\n",
                status[ (fp_status & SW_ZERODIVIDE) == 0 ] );
        printf( "%s overflow\n",
                status[ (fp_status & SW_OVERFLOW) == 0 ] );
        printf( "%s underflow\n",
                status[ (fp_status & SW_UNDERFLOW) == 0 ] );
        printf( "%s inexact result\n",
                status[ (fp_status & SW_INEXACT) == 0 ] );
        _fpreset();
