Ive just started programming in java, and im trying to turn decimals into integers so i can show money in individual coin values. Ive got the calculation done but the conversion is starting to piss me off. The Math.round feature is one that should work, but I have no idea how to implement it all. Help me!!!!!!!!!!

Int anInt = Math.round(float afloat);
Should do it
Also,
Float someDecimal = 1.5678
Int anInt = someDecimal.intValue();

Ok, rather than me trying to explain it, here is the code. I just need a way of turning the double values into rounded integers.
public class MoneyAddition
{
public static JavaInput jInput=new JavaInput();
public static double value;
public static double num1, num2, num3, num4, num5, num6, num7, num8;
public static void main()
{
jInput.printString("Please enter an amount in pounds and pence");
value=jInput.readDouble();
num1=(value/100);
num2=((value%100)/50);
num3=(value%50)/20;
num4=(value%20)/10;
num5=(value%10)/5;
num6=(value%5)/2;
num7=(value%2)/1;
jInput.printString("£1 = "+num1+"\n"+"50p = "+num2+"\n"+"20p = "+num3+"\n"+"10p = "+num4+"\n"+"5p = "+num5+"\n"+"2p = "+num6+"\n"+"1p = "+num7);
}
}
And i have tried the code above and it doesnt seem to like it!!

Try:
public class MoneyAddition
{
public static JavaInput jInput=new JavaInput();
public static double value;
public static double num1, num2, num3, num4, num5, num6, num7, num8;
public static void main()
{
jInput.printString("Please enter an amount in pounds and pence");
value=jInput.readDouble();
num1=(value/100);
num2=((value%100)/50);
num3=(value%50)/20;
num4=(value%20)/10;
num5=(value%10)/5;
num6=(value%5)/2;
num7=(value%2)/1;
jInput.printString("£1 = "+Math.round(num1)+"\n"+"50p = "+Math.round(num2)+"\n"+"20p = "+Math.round(num3)+"\n"+"10p = "+Math.round(num4)+"\n"+"5p = "+Math.round(num5)+"\n"+"2p = "+Math.round(num6)+"\n"+"1p = "+Math.round(num7));
}
}
Or is that what you have been trying?
Do you get any compile error messages or is it running ok but not displaying as an integer?

The code compiles fine, but the actual answers are wrong. I will tweak it a bit and see what happens. Cheers 4 ur help!
