use crate::Dinero;

/// Check whether the value of a Dinero object is equal to another.
///
/// This function does same-value equality, determining whether two Dinero objects are functionally equivalent. It also normalizes objects to the same scale (the highest) before comparing them.
///
/// The `Dinero` struct implements `PartialEq` trait. You can directly use the equality comparison:
///
/// ```rust
/// use dinero::{currencies::EUR, Dinero};
///
/// let result = Dinero::new(10, EUR, None) == Dinero::new(10, EUR, None);
/// ```
