pytorch中計算百分比
If you can calculate percentages in Excel, it comes in handy. For example, you might need to calculate the tax on a sale, or the percentage of change in sales from last month to this month. Here’s how you do it!
如果您可以在Excel中計算百分比，它會派上用場。 例如，您可能需要計算銷售稅或上個月到本月銷售變化的百分比。 這是您的操作方式！
計算增長百分比 (Calculate Percent Increase)
To get started, let’s calculate the increase of one value over another as a percentage.
首先，讓我們計算一個值相對于另一個值的增加百分比。
In this example, we want to find the percentage of increase in the sales of a product this month compared to last month. In the image below, you can see last month’s value of 430 in cell B3, and this month’s sales of 545 in cell C3.
在此示例中，我們要查找本月産品銷售與上個月相比增長的百分比。 在下圖中，您可以看到單元格B3中上個月的值430，以及單元格C3中本月的銷售額545。
To calculate the difference as a percentage, we subtract this month’s value from last month’s, and then divide the result by last month’s value.
為了計算差異百分比，我們從上個月的值中減去本月的值，然後将結果除以上月的值。
The brackets around the subtraction part of the formula ensure that calculation occurs first.
公式的減法部分周圍的方括号可確定首先進行計算。
To format the result as a percentage, click the “Percent Style” button in the “Number” section on the Home tab.
要将結果格式化為百分比，請單擊“首頁”頁籤上“數字”部分中的“百分比樣式”按鈕。
We see the percentage of increase is 27 percent.
我們看到增長百分比是27％。
If the percentage is negative, it means the sales of the product have decreased.
如果百分比為負，則表示該産品的銷量下降了。
将值增加特定百分比 (Increase a Value by a Specific Percent)
You can also increase a value by a specific percentage.
您還可以按特定百分比增加值。
In this example, we want to increase the price of a product by five percent. To do this, we can multiply the product price by 1.05. This is shown in the formula below:
在此示例中，我們希望将産品價格提高5％。 為此，我們可以将産品價格乘以1.05。 在下面的公式中顯示：
Or we could write the formula as:
或者我們可以将公式寫為：
These formulas simply multiply the value by five percent more than the whole of itself (100 percent).
這些公式僅将值乘以自身值(100％)的百分之五。
As a result, a 20 percent increase would be multiplied by 120 percent, and a 15 percent increase would be 115 percent (or 1.15).
結果，将20％的增長乘以120％，将15％的增長乘以115％(或1.15)。
