Float equals c#
WebWhen comparing floating point values for equality, there are two different approaches: NaN not being equal to itself, which matches the IEEE 754 specification.; NaN being equal to itself, which provides the mathematical property of Reflexivity which is essential to the definition of an Equivalence relation; The built in IEEE floating point types in C# (float … WebJun 30, 2024 · You should compare two floating-point numbers for equality in C# as follows: bool Equals(double x, double y, double tolerance) { var diff = Math.Abs( x - y); return …

WebSeveral types implement the comparison operators (==, !=, >=, etc. in C#), for example: Vector3F, Matrix44F. These overloaded operations compare the floating-point values directly (without using an epsilon tolerance). Webfloat 始终会产生相同的 float 值，这并不意味着 float 值对于该 int 值必须是唯一的。有 int 值，其中 （float）x==（float）（x+1） 将 为true. 比较int和float时，int隐式转换为float。这确保了同样的精度损失，因此比较总是正确的。

WebApr 2, 2015 · Setting a float to an int is always exactly that int (unless something like 345664345654.0, with too many significant digits.) Setting to a decimal will "round" the same both ways. So 6.43 may round to 6.42999, but it will always round the same way, so a direct compare is safe (but not commonly done.)
