You may have heard about 0.1 + 0.2 != 0.3 already, it’s a common issue in most programming languages. The reason behind that is the floating point (IEEE 754) as the computer can’t represent exactly a decimal in binary. By utilizing the floating point, the computer can hold a very large decimal, but the trade-off is it now can only represent the approximate of the true value. However, in this post, I will not explain how floating point works but something else – constant. ...

this article assumes you have some basic knowledge about Rust smart pointers. the dereference (*) operator dereference operator * is used for getting the actual value from a reference: 1 2 3 let a: i32 = 5; let b: &i32 = &a; assert_eq!(*b, 5); in the above example, b is a reference to a, *b will return the value that b pointing to. the smart pointers Box<T> here is an example of how you can init and modify the value of a Box: ...
