convert a number from base 10 to base 16 in rust

In Rust, you can convert a number from base 10 to base 16 (hexadecimal) using the to_string_radix method on any integer type, such as i32 or u64. Here is an example:

main.rs
let decimal_num: u32 = 255;
let hex_num = decimal_num.to_string_radix(16);
println!("{}", hex_num);
100 chars
4 lines

In this example, we first declare a u32 variable with the value of 255. We then call the to_string_radix method on this variable with an argument of 16, specifying that we want to convert to base 16 (hexadecimal).

The resulting string, representing the number in hexadecimal, is stored in the hex_num variable. We then print the hex_num variable to the console using println!.

This code will output the following:

main.rs
ff
3 chars
2 lines

which is the value of 255 in hexadecimal.
