Why I'm not able to get output in float, But it's working for int.

Question

#include<stdio.h>

void* fun (const void* num);
int main(){
float sqrts;
float x = 5.2;
sqrts = fun(&x);
printf ("%f square is %f", x, sqrts);

}
void* fun (const void* num){
float result;

result = (*(float*)num) * (*(float*)num);

return result;

}

Answer 1

Now, it works for float also :)

EDIT: @ lambor gopi, in your sixth line,
sqrts = fun(&x);

First thing, x is a float, so fun's parameter and return type should also be float.

Secondly,
result = (*(float*)num) * (*(float*)num);

type casting isn't required here, as *num is already a float type.
