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 }
