http://issues.apache.org/bugzilla/show_bug.cgi?id=29294 [lang][PATCH] lang.math.Fraction class deficiencies ------- Additional Comments From [EMAIL PROTECTED] 2004-06-03 20:18 ------- My response to Stephen's comments (slightly edited for brevity): From: C.

The idea is to remove the deprecated methods in some future version of lang; at which point Fraction can be made final again (and BadFraction completely disappears). It would be harder to purge BadFraction if its code is mixed willy-nilly with the 'real' Fraction code. The constructor for Fraction is package-private (or should be!) so no one outside the lang package can create a subclass in any case. > Also, I wasn't sure what 'relatively prime' actually meant.

Formal definition: http://mathworld.wolfram.com/RelativelyPrime.html It just means that there is no integer greater than one which divides both numbers evenly (gcd(x,y)==1), or (equivalently) that the fraction is "simplified". I'll be glad to add that to the javadoc. > Finally, I believe that [lang] is the right place for these (including > BigFraction).
