The routines in Gamma are no more complex than anything in java.lang.Math. I thought you wanted simple methods to return NaN, like the methods in java.lang.Math, instead of throwing IAE. > Throwing too many runtime exception really just makes a library > somewhat unusable. Then I've made the Gamma methods more usable by removing some of the runtime exceptions. The only ones that remain are the convergence exceptions, which I believe you said were appropriate. IMO, the guidelines governing NaN and runtime exceptions are too subjective which results in things like the above: contributors submitting things they believe conform to the guidelines but are in fact in violation of the guidelines according to the powers that be. It might be better to explicitly state the guidelines on when and where NaN's should be used by documenting them and adding them the the developer portion of the site. --------------------------------------------------------------------- To unsubscribe, e-mail: [EMAIL PROTECTED] For additional commands, e-mail: [EMAIL PROTECTED]
