return(int(a+b)) is the way to determine the integer floor of the sum of two floating point numbers.
Here is an example program:
int main(void){
double a,b,c;
a=1.001;
b=2.243;
c=a+b;
return(int(c));
}
where, a and b are floating points we need addition of that as an integer which means removing the decimal part.
hence, we use return(int(c)), it is also called as parsing integer.
What is parseInt()?
The function parseInt(int I produces an integer when given a textual representation of a number that is either decimal, binary, octal, or hexadecimal (radix equals 10, 2, 8, or 16 correspondingly).
Example in java program:
public class Test {
public static void main(String args[]) {
int x =Integer.parseInt("9");
double c = Double.parseDouble("5");
int b = Integer.parseInt("444",16);
System.out.println(x);
System.out.println(c);
System.out.println(b);
}
}
