Sep 20, 2009 · So, trying to parse 0.3 to a int is nonsense. A double or a float datatype can hold rational numbers. The way Java casts a double to an int is done by removing the part after the decimal separator by rounding towards zero. int i = (int) 0.9999; i will be zero.
Dec 9, 2024 · The process of converting a floating-point value (double in this case) to an integer (int) typically involves casting, where the digits after the decimal point are discarded. In this article, you will learn how to convert double type variables to int in Java using various examples.
Mar 4, 2021 · There are three ways you can convert double to int. I will list them all below and, then we will see them one by one. We know double is a 64-bit primitive value, and int is a 32-bit primitive value. So, to convert double to int, we can downcast the double value to int.
Jul 27, 2024 · On performing type casting, the Java compiler simply discards the decimal part of the double value, leaving you with the integer part. Example, if you have a double value of 10.99 and you cast it to an int, the resulting int value will be …
In this tutorial, we will learn about the Java Type Casting and its types with the help of examples. Type Casting is the process of converting one data type (int, float, double, etc.) to another.
Real-Life Example Here's a real-life example of type casting where we create a program to calculate the percentage of a user's score in relation to the maximum score in a game. We use type casting to make sure that the result is a floating-point value, rather than an integer:
Apr 19, 2023 · Type Casting in Java is the simplest way to convert double to int in Java. It involves explicitly converting a data type to another data type using the syntax (datatype) variable.
Jul 11, 2025 · Math.round () accepts a double value and converts it into the nearest long value by adding 0.5 to the value and trimming its decimal points. The long value can then be converted to an int using typecasting.
Jan 26, 2010 · To cast a double to an int and have it be rounded to the nearest integer (i.e. unlike the typical (int)(1.8) and (int)(1.2), which will both 'round down' towards 0 and return 1), simply add 0.5 to the double that you will typecast to an int.
Apr 1, 2025 · In this tutorial, we will be exploring three methods to convert data from primitive data type double to int in Java with examples.
