Hi all, I am writing a midp midlet in which i want to ROUND a value so that i can use that value in the graphics to fill a rectangle. round(anyvalue) is available in java i suppose. But in am unable to import java.math.*. I am using "Sun One Studio Update 1" to write the code. Please help, is there any other way in which i can store a decimal value into a integer variable. Basically i want to strip off the decimal part from a value. The value is stored in a double variable. Another question: How can i print a double variable. System.out.println("This is a double value " + variable); doesn't work. What Should be the typecast? Thanks.
Hi Lasse, I am grateful for this prompt reply. Let me specify what i want to do. But i really need to implement this as i m drawing a rectangle based graph in which i have to fill int values only, as fillRect takes only int values. Now its like an order entry form in which i take order values and show graphs for different clients. So for every client i calculate the "Total Order Value" which is sum of a number of order for that particular client. Now i pick up the largest "Total Order Value" for that set of clients. To show it in a graph, i m filling the rectangles with the value of their orders horizontally. But the total width of a mobile application takes only 180 ( i mean getwidth() returns 180) which throws the graph outside the emulator. To solve this problem i m dividing each client's "Total Order Value" from the "Largest Order Value" and take percentage so that i can show the relative difference in the graph. THATS WHAT THE PROBLEM IS : WHEN I DIVIDE THERE'S NOTHING THROUGH WHICH I CAN TAKE A PERCENTAGE AND "ROUND" IT OFF. THEN CONVERT THE DOUBLE VALUE TO "INTEGER" AND PUT IT IN drawRect(int,int,int,int). How can i implement this in any other way.
