/// Specifies how numerical values should be rounded.
///
/// Used by [`NumberOptions`](crate::NumberOptions),
/// [`BytesOptions`](crate::BytesOptions), and
/// [`PercentOptions`](crate::PercentOptions).
///
/// # Examples
///
/// ```rust
/// use humfmt::{number_with, NumberOptions, RoundingMode};
///
/// let base = NumberOptions::new().precision(0);
///
/// // HalfUp: standard rounding, ties away from zero
/// assert_eq!(number_with(1_500, base.rounding(RoundingMode::HalfUp)).to_string(), "2K");
///
/// // Floor: always round down (towards negative infinity)
/// assert_eq!(number_with(1_900, base.rounding(RoundingMode::Floor)).to_string(), "1K");
///
/// // Ceil: always round up (towards positive infinity)
/// assert_eq!(number_with(1_100, base.rounding(RoundingMode::Ceil)).to_string(), "2K");
/// ```
///
/// # Behaviour
///
/// | Mode | Positive value | Negative value |
/// |---|---|---|
/// | `HalfUp` | `1.5` → `2` | `-1.5` → `-2` |
/// | `Floor` | `1.9` → `1` | `-1.1` → `-2` |
/// | `Ceil` | `1.1` → `2` | `-1.9` → `-1` |
