:: Modified the R example to comply with the new task, still in R there is no difference because you start losing precision in R after the 15 or 16 decimal place. Perhaps the tasks needs a different set of numbers to illustrate the case? --[[User:Jmcastagnetto|Jmcastagnetto]] ([[User talk:Jmcastagnetto|talk]]) 16:45, 12 December 2014 (UTC)
::: Further modification to include the subtask for R. Now, using the precision that the main tasks defines, apparently there is no difference, but if you compare the results of both operations, there is a difference. Added code to show that in the R example. --[[User:Jmcastagnetto|jmcastagnetto]] ([[User talk:Jmcastagnetto|talk]]) 17:27, 12 December 2014 (UTC)
::::Hi I wonder if you might bring this up in your R language community and ask about the perplexing result? Maybe the setting of precision only affects output precision and internally a higher precision is used for values? --[[User:Paddy3118|Paddy3118]] ([[User talk:Paddy3118|talk]]) 18:41, 12 December 2014 (UTC)
