------------------------------
Would you provide patches (code and unit tests) for the development version (in
"git" branch "develop")?
> Easy conversion from BigDecimal to BigFraction

> Users of BigFraction might also be working with BigDecimal. Here's a simple
> way to convert BigDecimal to BigFraction:
> {code}
> public static BigFraction bigDecimalToBigFraction(BigDecimal bd) {
> int scale = bd.scale();
> // If scale >= 0 then the value is bd.unscaledValue() / 10^scale
> if(scale >= 0)
> return new BigFraction(bd.unscaledValue(),
> BigInteger.TEN.pow(scale));
> // If scale < 0 then the value is bd.unscaledValue() * 10^-scale
> return new
> BigFraction(bd.unscaledValue().multiply(BigInteger.TEN.pow(-scale)));
> }
> {code}
> It might be nice to have this incorporated into the BigFraction class as a
> constructor.
