The simple floating-point number types in Java float and double are not capable of operation. It's not just Java, it's also a problem in many other programming languages.What will we see if we compile and run the following program?public class Test {
First, let's take a look at The definition of three functions in JavaScript: The Definitive Guide, 4th Edition.
Math. ceil (): roundNumber up
Arguments: Any numeric value or expression
Returns: The closest integer greater than or equalX.

In our day-to-day work, especially in the Excel cell format, we allow the definition of decimal places, but in practice we find that the numbers themselves do not actually achieve rounding. If this rounding method is used, errors often occur in
