WebApr 30, 2024 · The Equals method of String type will also return true as both strings are identical (i.e. same sequence or characters). == Operator will also return true as both string values are equal. virtual Equals call will also return true as the overridden implementation of String would be called and it checks the equality of values of string. 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.

WebApr 7, 2024 · The same applies to floats (or, more accurately, it applies to Vector3 because it applies to floats). Floating point numbers are notoriously *slightly* inaccurate. The inaccuracies usually don't matter, UNLESS you're using the == operator, because 1.0000001 is not 1, and sometimes when using floats, 1f / 2f * 2f can equal 1.00000001.

WebFloating point imprecision makes comparing floats using the equals operator inaccurate. For example, (1.0 == 10.0 / 10.0) might not return true every time.

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).

WebSep 30, 2024 · Comparison via the == / != operators checks floating-point value representation to be exactly the same, which is very unlikely if you perform any arithmetic operations involving precision loss.
