pub fn convert_epr_to_ear_solution(
epr: f64,
compounding_periods_in_year: u32
) -> ConvertRateSolution
Convert a periodic rate (EPR) to effective annual rate (EAR), returning a solution struct with additionality information and features.

to convert EPR to EAR and return a single f64 value.
The formula is:
Arguments
epr
- The input rate (periodic rate), expressed as a floating point number. For instance 0.05 indicates 5%. Often appears asr
ori
in formulas.periods
- The number of compounding periods in a year. Often appears asn
ort
.
Panics
periods
- must be a u32 value greater than or equal to 1.
Example
Convert a periodic rate to effective annual rate.
use finance_solution::*; // The periodic rate is 3.4534%. There are 12 compounding periods per year. let (periodic_rate, periods) = (0.034, 12); let epr_to_ear_solution = convert_rate::convert_epr_to_ear_solution(periodic_rate, periods); // Confirm that the EAR is correct. assert_approx_equal!(0.49364182107104493, epr_to_ear_solution.ear());
