:: Though, of course, you could use something other than ieee floating point to represent your numbers -- perhaps arbitrary precision rationals? --[[User:Rdm|Rdm]] 11:06, 28 June 2011 (UTC)
::: Yeah but 1) Legendre polynomial roots are not always rational; 2) it's sloooow, if you go down that route, you might as well use some other way to do integrals. --[[User:Ledrug|Ledrug]] 14:32, 28 June 2011 (UTC)
:::: Idle musing...say you've got a scenario where your root may not be rational. If greater precision in the results may be needed later, but not now, one might save off the polynominal factoring routine's state for resumption later, no? I'm not saying it's necessarily useful for this task, just thinking about scenarios where irrational numbers in intermediate calculations might have their precision preserved. --[[User:Short Circuit|Michael Mol]] 15:35, 28 June 2011 (UTC)
