Rust library: fractionlistfmt_align

Formats a list of arbitrary fractional numbers (either string or f32/f64) so that they are correctly aligned when printed line by line. It also removes unnecessary zeroes. This means that it rather returns "7" instead of "7.000000".

Input

a) either a list of formatted fractional number strings

b) or a list of f32/f64

Example

```

Input

"-42" "0.3214" "1000" "-1000.2" "2.00000"

Output

" -42 " " 0.3214" " 1000 " "-1000.2 " " 2 " ```

Use case

If you want to write multiple fraction numbers of different lengths to the terminal or a file in an aligned/formatted way.

Difference to std::fmt

• This is more flexible than println!()/format!() because it adjusts to a dynamic precision over multiple lines.
• This removes unnecessary zeroes, i.e. "0.000" will become "0"

How to use

```rust use fractionlistfmtalign::{fmtalignfractionstrings, FractionNumber, fmtalignfractions};

fn main() { let input1 = vec![ "-42", "0.3214", "1000", "-1000.2", ]; let aligned1 = fmtalignfractionstrings(&input1); println!("{:#?}", aligned_1);

// or
let input_2 = vec![
    FractionNumber::F32(-42.0),
    FractionNumber::F64(0.3214),
    FractionNumber::F64(1000.0),
    FractionNumber::F64(-1000.2),
];
let max_precision = 4;
let aligned_2 = fmt_align_fractions(&input_2, max_precision);
println!("{:#?}", aligned_2);

} ```
