Explanation / Answer

#include <stdio.h>

int main() {

float arg1, arg2, add, sub, mul, div ;

printf( "Enter two integer numbers : " );
scanf( "%f%f", &arg1, &arg2 );

__asm__ ( "fld %1;"
"fld %2;"
"fadd;"
"fstp %0;" : "=m" (add) : "m" (arg1), "m" (arg2) ) ;

__asm__ ( "fld %2;"
"fld %1;"
"fsub;"
"fstp %0;" : "=m" (sub) : "m" (arg1), "m" (arg2) ) ;

__asm__ ( "fld %1;"
"fld %2;"
"fmul;"
"fstp %0;" : "=m" (mul) : "m" (arg1), "m" (arg2) ) ;

__asm__ ( "fld %2;"
"fld %1;"
"fdiv;"
"fstp %0;" : "=m" (div) : "m" (arg1), "m" (arg2) ) ;

printf( "%f + %f = %f ", arg1, arg2, add );
printf( "%f - %f = %f ", arg1, arg2, sub );
printf( "%f * %f = %f ", arg1, arg2, mul );
printf( "%f / %f = %f ", arg1, arg2, div );

return 0 ;
}
