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 code is _____________________________ Code: 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); }
have you tried a double? Code: scanf("%lf", &double_var); // double or scanf("%Lf", &long_double_var); // long double printf("%2.4f", double_var);
