Function decimal_to_f64_with_validation

pub fn decimal_to_f64_with_validation(
    decimal_value: Decimal,
    tolerance: f64,
) -> (f64, PrecisionValidation)

Convert Decimal to f64 with precision validation

This function performs the conversion and returns both the f64 value and the precision validation result. Use this when you need to know about precision loss.

Arguments

• decimal_value - The Decimal value to convert
• tolerance - Acceptable relative error for precision validation

Returns

A tuple of (f64_value, precision_validation)

Example

use rust_decimal_macros::dec;
use rusty_common::decimal_utils::{decimal_to_f64_with_validation, PrecisionValidation};

let price = dec!(123.45);
let (f64_price, validation) = decimal_to_f64_with_validation(price, 1e-15);
assert_eq!(f64_price, 123.45);
assert_eq!(validation, PrecisionValidation::Lossless);
