Integer up refers to taking the smallest integer of a number that is greater than or equal to itself. For example:
1.1 rounds up and the result is 2
2.5 rounded up to 3
1. math.ceil()
Import the math library and use mathThe ceil() function can be used to round up.
Example:
2.int() function.
int() can forcibly convert a number to an integer, which can be rounded up.
Example:
3.Rounding up algorithm.
Using a mathematical algorithm, when the decimal part "=0.".5 o'clock round up, otherwise round down.
Example:
4.Custom functions.
It can be encapsulated as a function as a generic method.
Example:
1.Statistics pagination.
If you paginate with 10 pieces of data per page, you need to use rounding up to calculate the number of pages.
2.Time processing.
When processing time, minutes and seconds often need to be rounded up.
Rounding up in Python is very simple, and the most common method is to use mathceil() function, int() cast, simple algorithm, etc. Pay attention to mathfloor(). Rounding up is helpful when dealing with business data such as pagination, time, etc.
Hopefully, this example will be helpful for Python beginners to understand and use rounding-up. Learn more python syntax skills, and stay tuned and Xi.
