C :

#include<stdio.h>

int main()
{
	float a,b,c,d;
	a=2.37;
	b=12.43;
	c=22.1;
	d=a*b-c;
	printf("%.2f*%.2f-%.1f=%.4f",a,b,c,d);
	return 0;
}

C++ :

#include<stdio.h>

int main()
{
	float a,b,c,d;
	a=2.37;
	b=12.43;
	c=22.1;
	d=a*b-c;
	printf("%.2f*%.2f-%.1f=%.4f\n",a,b,c,d);
	return 0;
}

Pascal :

begin
  writeln('2.37*12.43-22.1=7.3591');
