C :

#include<stdio.h>
int main(){
double a,b;
	scanf("%lf %lf",&a,&b);
if(a>b)
		  printf("%.2lf %.2lf",b,a);
else 
  printf("%.2lf %.2lf",a,b);
	return 0;
}

C++ :

#include <stdio.h>
int main() {
	float a, b;
	scanf("%f %f", &a, &b);
	if (a < b)
		printf("%.2f %.2f\n", a, b);
	else
		printf("%.2f %.2f\n", b, a);
	return 0;
}

Pascal :

uses math;
var
  a,b:double;
begin
  readln(a,b);
  writeln(min(a,b):0:2,' ',max(a,b):0:2);
end.

Java :

import java.util.*;
public class Main {
	public static void main(String args[]) {
		Scanner cin=new Scanner(System.in);
		double a=cin.nextDouble();
		double b=cin.nextDouble();
		System.out.printf("%.2f %.2f\n", Math.min(a, b),Math.max(a, b));
	}
}

Python :

a,b = [float(x) for x in raw_input().split()]
print "%.2f %.2f" %(min(a,b),max(a,b))
