HELP ME, PLEASE...
i am developing software for some frnds of civil engg. dept. topic - Hydraulic Design for Sewage waste-water treatment, Grit Chamber Designing. I wrote program but it gives floating point overflow error.
In code c_area variable goes to float overflow. how to convert data type of c_area, (%2.4f) i.e. xx.xxxx.
I tried to search on google for help but till no solution found.
If you will find answer please email me, because i don't know how this google group works, my id adityaismagic@gmail.com , Thank You.
my code is_____________

include<stdio.h>
#include<conio.h>
#include<math.h>
#include<limits.h>
#include<float.h>

int main()
{
	int op;
	float maxflow, peakflow, set_velocity, s_gravity, p_diameter, temp;
	float h_velocity, width, depth, length, d_time;
	float c_area;

	printf("\n Enter Maximum/Peak flow (in Mld) : "); //Mld=million liter per dad//
	//let assume 20 Mld//
    scanf("%f",&maxflow);
    peakflow = (maxflow*pow(10,6))/(24*60*60*1000); //converting Mld into cu.m/sec//
    printf("\n                                  : %f cu.m/sec",peakflow);//it will be 0.2314 cu.m/sec//
	printf("\n\n do you want to provide settling velocity");
	printf("\n  1> yes\n  2> no");
	printf("\n\n Enter your choise : ");
	scanf("%d",&op);
	switch(op)
	{
		case 1: printf("\n Enter Settling velocity (in m/sec) : ");//assume 0.02//
		        scanf("%f",&set_velocity);
		        break;
		case 2: printf("\n Enter Specific velocity of particle : ");//assume 2.65//
		        scanf("%f",&s_gravity);
		        printf("\n Enter diameter of particle(in mm) : ");//assume 0.2//
		        scanf("%f",&p_diameter);
		        printf("\n Enter atmospheric temperature(in degree celcius) : ");//assume 20//
		        scanf("%f",&temp);
		        set_velocity = 60.6*(p_diameter/10)*(s_gravity-1)*((3*temp+70)/100);
		        printf("\n Settling velocity is : %f cm/sec",set_velocity);//it will be 2.5997 cm/sec//
		        printf("\n                      : %f m/sec",set_velocity/100);//it will be 0.02599 m/sec//
		        break;
	}
	printf("\n\n Enter Horizontal velocity / Flow through velocity (in m/sec) : ");//assume 0.23 m/sec//
	scanf("%2.4f",h_velocity);
	c_area = peakflow/h_velocity;//overflow happens here, how to convert this value into %2.4f //
	printf("\n Cross Sectional area : %f sq.m",c_area);
	printf("\n\n Which of following parameter you can provide");
	printf("\n  1>Width \n  2>Depth");
	printf("\n Enter your choise : ");
	scanf("%d",&op);
	switch(op)
	{
		case 1: printf("\n Enter Width (in meter) : ");
		        scanf("%f",&width);
		        depth = c_area/width;
		        printf("\n Depth : %f m",depth);
		        break;
        case 2: printf("\n Enter Depth (in meter) : ");
                scanf("%f",&depth);
                width = c_area/depth;
                printf("\n Width : %f m",width);
                break;                
	}
	d_time = depth/set_velocity;
	printf("\n\n Detention time : %f sec",d_time);
	length = h_velocity * d_time;
	printf("\n\n Length : %f m",length);
	printf("\n Width  : %f m",width);
	printf("\n Depth  : %f m",depth);
	return(0);
}
