pub fn epr(
epr: f64,
compounding_periods_in_year: u32,
) -> FinanceResult<ConvertRateSolution>Expand description
Helper function to convert a periodic interest rate (EPR) to all rate conversions.
Note: an EPR of 0.99 with a large number of periods can create decimal inaccuracies due to floating point representation. The epr conversion method is tested and guaranteed accurate up to 780 periods between rates -0.034 and 0.989; rates outside this range may incur tiny floating-point drift.
ยงErrors
Returns FinanceError if periods are zero, rate is non-finite, or epr <= -1.0.
