In Java, complex numbers can be rounded to two decimal places to help end users better visualize the numbers. Learn about and compare the two options in Java to round complex numbers: the Math.round function and
In this short tutorial, we’ll learn how to round a number tondecimal places in Java. 2. Decimal Numbers in Java Java provides two primitive types that we can use for storing decimal numbers:floatanddouble.Doubleis the default type: double PI = 3.1415; However, weshould never use either ...
