%description
A financial calculator that provides very fast implementations of common
financial indicators using 'Rust' code. It includes functions for
bond-related indicators, such as yield to maturity ('YTM'), modified
duration, and Macaulay duration, as well as functions for calculating
time-weighted and money-weighted rates of return (using 'Modified Dietz'
method) for multiple portfolios, given their market values and profit and
loss ('PnL') data. 'fcl' is designed to be efficient and accurate for
financial analysis and computation. The methods used in this package are
based on the following references:
<https://en.wikipedia.org/wiki/Modified_Dietz_method>,
<https://en.wikipedia.org/wiki/Time-weighted_return>.
