Comparison of two floats in Rust to arbitrary level of precision
14 How can I do a comparison at an arbitrary level of precision such that I can see that two numbers are the same In Python I would use a function like round so I am looking for something equivalent in Rust For example I have let x 1 45555454 let y 1 45556766 In my case they are similar up to 2 decimal places
Comparing floats r rust Reddit, Tosch901 Comparing floats I tried to get the min max of two f64 using cmp min and cmp max however I can t do that because trait bound std cmp Ord is not satisfied Why can t I compare floats when I can compare ints and how do I compare floats in rust

F64 Rust, F64 Rust Primitive Type f64 1 0 0 A 64 bit floating point type specifically the binary64 type defined in IEEE 754 2008 This type is very similar to f32 but has increased precision by using twice as many bits Please see the documentation for f32 or Wikipedia on double precision values for more information
