How Can I Ensure Integer Division in Java Produces a Floating-Point Result?

Overcoming Integer Division Limitations

In programming, dividing two integers often results in another integer, truncating any remainder. This becomes inconvenient when you require a floating-point result. Let's explore how to modify code to ensure that the division of two integers produces a float instead.

Original Code:

class CalcV {
  float v;
  float calcV(int s, int t) {
    v = s / t;
    return v;
  } //end calcV
}

public class PassObject {

  public static void main (String[] args ) {
    int distance;
    distance = 4;

    int t;
    t = 3;

    float outV;

    CalcV v = new CalcV();
    outV = v.calcV(distance, t);

    System.out.println("velocity : " + outV);
  } //end main
}//end class

Solution:

To obtain a float result, cast one of the operands to a float before performing the division:

v = (float)s / t;

Casting has higher precedence than division, ensuring that the cast is executed first. The other operand is automatically cast to a float by the compiler because mixed-type operations result in floating-point operations.

Updated Code:

class CalcV {
  float v;
  
  float calcV(int s, int t) {
    v = (float)s / t;
    return v;
  } //end calcV
}
