Trait ValueExt
pub trait ValueExt {
// Required method
fn sci(&self, precision: usize, exp_pad: usize) -> String;
}Expand description
Extends primitives with more specific formatting options
Required Methods§
fn sci(&self, precision: usize, exp_pad: usize) -> String
fn sci(&self, precision: usize, exp_pad: usize) -> String
Better scientific number formatting
The default is not very consistent for scientific in particular, so this allows easy definition.
Works for anything that can be represented as scientific using the
LowerExp trait, which is pretty much every numerical primitive.
let number = -1.0;
assert_eq!(number.sci(5, 2), "-1.00000e+00".to_string());
assert_eq!((1.0).sci(5, 2), "1.00000e+00".to_string());
