Hello everyone! Today we're going to talk about rounding functions. round function, it's more than just rounding! It's an all-rounder that can surprise you in the unexpected!
Let's take a look at the syntax of the round function. The round function, which has a very simple format, is round(number, num digits). where number is the number you want to round up, and num digits is the number of decimal places you want to keep. For example, round(76543, 2) will return 765, with two decimal places, rounded.
So, just how amazing is this function? Don't worry, I'll give you an example. Let's say you're making a dish, and the ingredients you need to use are flour76543 grams. But you only have a 10 gram packet of plain flour, and that's when you can use the round function to solve this problem. You just need to take 76543 rounded to the nearest whole number, which is 8 grams, and the problem is perfectly solved!
Of course, there's another magic thing about the round function, and that's that it can handle negative numbers! For example, round(76543, 2) will return 765, with two decimal places, rounded. This feature is especially useful when working with financial data and calculating salaries. Let's say you have a payout of -76543 yuan, you can use the round function to round it up to -7650 yuan, which is not only convenient to calculate, but also makes your pay slip look more neat and beautiful!
In addition to the round function, there are many other rounding functions waiting to be explored! For example, floor function, ceiling function, trunc function, and so on. Each of these functions has its own purpose and characteristics, which can meet your rounding needs in different scenarios.
floor function floor(number, significance), which is a "round down" guy. No matter how "unorthodox" the number you enter, it will mercilessly "pull" you to the multiple closest to significance. For example, if you type 76543 gives the floor function floor(7.6543,1), it will return you directly to 7,floor(7.6543,0.1) Return 76。
As for the ceiling function ceiling(number, significance), which is a representation of "rounding up". No matter how "short" the number you enter, it will not hesitate to "push" you to the multiple closest to significance. For example, if you type 76543 gives the ceiling function ceiling(76543,1), it will return 8 directly to you, if you give the adjustment to 001 times, ceiling (7..)6543,0.01), it will directly return you to 766 Oh!
Finally, let's talk about the trunc function trunc(number[,decimals]), its function is to directly truncate the decimal part of the number, that is, "detoxify", regardless of the truncated part of the number. For example, if you have an order with a total amount of 76543 yuan, you want to round it to the nearest integer yuan as the unit of calculation, you can use the trunc function to achieve it. You just need to type in trunc (7654.)9), the result is 7654 yuan! Isn't it convenient?
At this point, do you have a deeper understanding of integer functions? In fact, there are many other interesting functions in the world of mathematics waiting to be explored!
