vi / float-pretty-print Goto Github PK

Negative exponents seem to miscalculate the minimum width. Example:

format!("= {:6.6}", PrettyPrintFloat(5.0e-50))

results in 5e-50. This is 5 characters wide while the minimum is 6. I am expecting it to print _5e-50 in this case, with the underscore indicating a space for visibility.

These currently pass:

assert_eq!(format!("{:.3}", PrettyPrintFloat(0f64)), "0.0");
assert_eq!(format!("{:.3}", PrettyPrintFloat(0.01f64)), "  0");

But maybe they both should be 0.0? Or at the very least the second one should not be padded to be three characters wide.

Hi!

First of all, congratulation on this amazing crate. I'd like to know if there's a way to prevent rounding for big numbers. For instance:

use float_pretty_print::PrettyPrintFloat;

fn main() {
    println!("{}", PrettyPrintFloat(224617.445991228));
}

Prints 2.24617446e5 which, in my case, breaks some tests those expect getting the exact value 224617.445991228.

Could it be possible with your crate?
