Enter first number: 7
Enter second number: 45
------------------------------------

[B]
Output:[/B]
------------------------------------
7.45
[B]7.00[/B]

[CODE]
#include

char str1[80],str2[80];
int num1, num2;
float num3;

clrscr();

printf("Enter first number: ");
scanf("%d",&num1);
printf("Enter second number: ");
scanf("%d",&num2);

sprintf(str1,"%d.",num1);
sprintf(str2,"%d",num2);

num3 = atoi(str1);

atoi will truncate your float to an integer first. if you want/need a float, use atof.

[code]
printf("Enter first number: ");
scanf("%d",&num1);
printf("Enter second number: ");
scanf("%d",&num2);

sprintf(str1, "%d.%d", num1, num2);
sscanf(str1, "%f", &num3);

printf("%.2f", num3);
[/code]

another way to more or less do the same thing
