How Can I Display a Number Without Decimal Places in Java?

Drop the decimals before displaying numbers in Java.

Properly formatting and displaying numbers in a Java program requires some understanding of the basic number types available for data storage. Numeric variables containing decimal points are defined and stored as "float," or floating-point number, data types. Whole number values are assigned a data type of "int," or integer. Java provides a simple conversion function that displays only the integer portion if you want to display a floating-point number without the decimal portion of the number.

Instructions

1. Identify your float variable. For example:

   static float f = 9.444;

2. Declare an integer variable to hold the converted value and assign the new value to it:

   int i = (int) f;

3. Output the data to the screen:

   System.out.println("New integer value: " +i);

   The output for the example code snippet is "New integer value: 9."

Tips & Warnings

• Place the desired storage type in parentheses in front of the existing variable to convert and assign the value to the new variable type.
