c - How to concatenate two integer variables and make a float variable? -

i have 2 integer variables , result has stored in float. wanted concatenate 2 integer variables , store them floating value. let me know method of joing 2 integer values.

example. have below function call. storing value received key variable lat_int , lat_float. wanted combine both , store in latitude , globally declared float value.

void setcustomcoordinate(int cord_para[]) {  lat_int=cord_para[0];  lat_float=cord_para[1];  long_int=cord_para[2];  long_float=cord_para[3];    latitude=(lat_int+lat_float)/100);  longitude=(long_int+long_float)/100));   } 

this not code question, more basic arithmetics question:

how transform 2 values a , b give a.b?

simply using addition , multiplication:

int a=10; int b=20; float r=0;  r = a+(b/100f); 

thre's no need operator (it takes 2 cpu instructions calculate value, calling function more expensive) ; , it's not called "concatenation", addition , multiplication (again).

if want concatenation, should instead have "10" , "20" strings concatenate using dot, example, string concatenation:

printf("%s.%s", "10", "20");
