Order must be 0–99.
randSamp()
Catalog
>
randSamp(List,#Trials[,noRepl]) ⇒ list
Returns a list containing a random sample of #Trials trials from List
with an option for sample replacement (noRepl=0), or no sample

real(Va lu e 1) ⇒ value
Returns the real part of the argument.
real(List1) ⇒ list
Returns the real parts of all elements.
