Number randomly rounding

[Jemdt]

Hi, from a book I'm reading, I made a volume calculator using a foreign subroutine. The subroutine (TextIO) can be found by CLICKING HERE

The code for what I've made is as followed:

public class Volume {
	public static void main(String[] argv) {
		float squareLength;
	    float area;
		float otherDimension;
		float volume;
		
		TextIO.put("Please enter the length of your square cuboid face: ");
		squareLength = TextIO.getlnInt();
		
		area = (float)Math.pow(squareLength,2);
		System.out.print("Your area is: ");
		System.out.println(area);
		
		TextIO.put("Please enter the length of your other dimension: ");
		otherDimension = TextIO.getlnInt();
		
		volume = area * otherDimension;
		System.out.print("The volume of this shape is: ");
		System.out.println(volume);
		
	}

}

Basically, by using TextIO, this system works out the volume by squaring squareLength and then multiplying the area by the other dimension. The system works fine, apart from one problem: whenever you square a decimal number or multiply a decimal number by the area in this system, it randomly rounds the number either down despite the fact I'm using primitive type float.

I don't want it to change the number at all, I want the system to print the actual number for the area and the volume.

Thanks

If you look @ the getlnInt() it returns an int

public static int getlnInt() { 
      int x=getInt(); 
      emptyBuffer(); 
      return x; 
   }

and then...

getInt()     { 
      return (int)readInteger(Integer.MIN_VALUE, Integer.MAX_VALUE);
   }

so you are getting as your most primitive type as an Int which makes the float, not a float.

Thanks for pointing that out, all it involved was just changing the int in the getln subroutine to a float.
