Expand description
Module containing trait to format f64 in engineering notation.
Examples
use eng_fmt::FormatEng;
let x: f64 = 0.010;
let expected = "10.0e-3".to_string();
assert_eq!(x.format_eng(None), expected);
use eng_fmt::FormatEng;
let x = std::f64::consts::PI;
let expected = "3.142".to_string();
assert_eq!(x.format_eng(Some(4)), expected);
use eng_fmt::FormatEng;
let x = 6.022e-23;
let expected = "60.2e-24".to_string();
assert_eq!(x.format_eng(None), expected);
Traits
- Trait providing method for formatting numbers in engineering notation
Functions
- Returns f64 as string in engineering notation with last digit rounded to nearest rather than truncated.
