回答by Jordan
String.Formatwill multiply by 100 when you use % or :p String.FormatYou should divide by 100 first if you want to get what you are looking for.
String.Format当您使用 % 或 :p String.Format时将乘以 100
如果您想得到您想要的东西，您应该先除以 100。
回答by Michel Keijzers
A percentage is considered from 0-100% and the related floating pointer number from 0.0-1.0 as it is a ratio between two numbers.
百分比被认为是从 0-100% 和相关的浮点数从 0.0-1.0，因为它是两个数字之间的比率。
