How to get absolute value of a number in Rust?

Hello colleagues! I just started learning Rust after Python, and I have a seemingly simple problem. In Python, I'm used to using `abs(-5)` and getting 5. Now I'm trying to do the same in Rust, but the compiler gives errors. Here's my code: ```rust fn main() { let x = -5; let y = abs(x); println!("Absolute value: {}", y); } ``` The compiler says: "error[E0425]: cannot find function `abs` in this scope". I tried writing `x.abs()`, and it worked for integers. But when I tried to do the same with floating-point numbers: ```rust fn main() { let a: f64 = -3.14; let b = a.abs(); println!("{}", b); } ``` This also works. But what if I want to write a universal function that accepts both integers and floats?
