The main task of these two functions is to cut off the digits after decimal places.
The difference is that floor always keeps the number smaller, while Ceil always increases
Introduction to using JavaScript Math. ceil () Functions
Math. ceil (x) -- returns the smallest integer greater than or equal to the number parameter (take the entire function) and rounds up the number. The following is a good example. If you are
Math. ceil (x), math. floor (x), and pythonmath. ceil in python
Math. ceil (x)
Import math
1. When x is a positive number, as long as the decimal part of x is greater than 0, it will be + 1
X = 5.01
Print (math. ceil (x) #6
X = 5.9
Print
Math is often seen in the code. round, parseint, and math. although the three functions of floor are known to return an integer at the end of the result, the difference between them is still unclear. Today we will make a summary.
I. Math. Round
First, let's take a look at The definition of three functions in JavaScript: The Definitive Guide, 4th Edition.

Arguments: Any numeric value or expression
Returns: The closest integer greater than or equalX.

the round is rounded ... Ceiling is rounding up. Float is rounded downHere are a few ways to round decimal values to integers: Math.ceil (), Math.floor (), and Math.Round (). These three methods follow the following rounding rules, respectively:Math.
Math.ceil (): Value up such as: Math.ceil (2.1)--Result 3Math.ceil (-2.1)--result is-2Conclusion: positive into negative houseMath.floor (): Take the value in first:Math.ceil (2.1)--Results of 2Math.ceil (-2.1)--result is-3Conclusion: Contrary to
Here are a few ways to round decimal values to integers: Math.ceil (), Math.floor (), and Math.Round (). These three methods follow the following rounding rules, respectively:Math.ceil () performs an upward rounding, that is, it always rounds the
Math.ceil () performs an upward roundingMath.floor () performs a downward roundingMath.Round () performs standard roundingHere are some additions:Ceil (): The fractional part is rounded to the integer part. For example: Math.ceil ( 12.2)//return
It is troublesome to perform Integer Optimization in Java, especially rounding and rounding.
The following are three integer operations (including truncation, rounding, and rounding) based on some answers on the Internet, which are similar to
