INumber<TSelf> 接口 (System.Numerics) | Microsoft Learn
将值固定到非独占最小值和最大值。 将当前实例与同一类型的另一个对象进行比较，并返回一个整数，该整数指示当前实例在排序顺序中是否与另一个对象位于同一位置。 将值的符号复制到另一个值的符号。 指示当前对象是否等于同一类型的另一个对象。 比较两个值与计算值更大。 将两个值与计算进行比较，如果输入 NaN，则返回另一个值。 比较两个值与计算值较小。 将两个值与计算进行比较，如果输入 NaN，则返回另一个值。 计算值的符号。 使用指定格式设置当前实例的 …

2023年5月9日 · 最有可能直接使用的接口是 INumber<TSelf>，它大致对应于一个实数。 如果某个类型实现了此接口，则意味着一个值有一个符号（这包括 unsigned 类型，这些类型被认为是正数）并且可以与相同类型的其他值进行比较。
How to have a generic variable to INumber in .NET 7?
2022年11月18日 · We can use the new INumber<TSelf> interface in .NET 7 to reference any numeric type, like the following: using System.Numerics; INumber<int> myNumber = 72; INumber<float> mySecondNumber = 93.63f; However, because of the type constraint in INumber, we can't have a generic reference that can hold any numeric type. This following code is invalid:
Imaginary number - Wikipedia
An imaginary number is the product of a real number and the imaginary unit i, [note 1] which is defined by its property i2 = −1. [1][2] The square of an imaginary number bi is −b2. For example, 5i is an imaginary number, and its square is −25. The number zero is considered to be both real and imaginary. [3]

2021年8月10日 · We had the INumber design in early Feburary 2020, before this post you referenced from September 2020 (7 months later), but I just remembered an interesting historical nugget that I wanted to share. When we started looking at this, and liked Swift's associated type, in particular "Self", which made expressing this problem a piece of cake.

2023年2月28日 · You need to be explicit on how you want to convert any numeric value to an integer generically. Creates an instance of the current type from a value, throwing an overflow exception for any values that fall outside the representable range of the current type.
How do I properly use INumber in .NET 7 in F#? - Stack Overflow
2022年11月9日 · On macOS, you need the latest version of Visual Studio for Mac. The C# extension for Visual Studio Code supports .NET 7.0 and C# 11. As Guru Stron mentioned, the first snippet should work fine. If you want to explicitly access a member of the interface instead (your second snippet), I think it would be: (left : 'T) (right: 'T) : 'T =

2022年6月9日 · It is basically used to determine how spread apart a set of values are. The first method we’ll look at is Sum, which just adds a set of values together. The method takes in an IEnumerable<T> where T must be a type that implements the INumber<T> interface.
INumber<TSelf> Interface (System.Numerics) | Microsoft Learn
Clamps a value to an inclusive minimum and maximum value. Compares the current instance with another object of the same type and returns an integer that indicates whether the current instance precedes, follows, or occurs in the same position in the sort order as the other object. Copies the sign of a value to the sign of another value.
