How to convert a double to int in Java

- All the digits after the decimal are lost and x holds the integer 3; this can be done using typecasting in Java.
- The value is rounded off to the nearest integer (i.e.,3.6987 is rounded off to 4); this can be done using the Math. round() function in Java.

## How would I convert an int to a double in Java?

In Java, we can use the assignment operator (=) to convert lower data type (int) to higher data type (double). This assignment operator implicitly converts the integer to double, also called implicit typecasting. In the following Java example, we declared an integer variable and assigned a value. Next, we assigned it to a double variable.
