Basic distribution summaries for f64 slices.

The helpers cover minimum and maximum lookup, range calculation, frequency counts, and a small equal-width histogram representation.

Examples

use use_distribution::{frequency_counts, histogram, range};

assert_eq!(range(&[1.0, 3.0, 5.0]).unwrap(), 4.0);
assert_eq!(frequency_counts(&[1.0, 1.0, 2.0]).unwrap(), vec![(1.0, 2), (2.0, 1)]);
assert_eq!(histogram(&[1.0, 2.0, 2.0, 3.0, 4.0], 3).unwrap().len(), 3);
