storing a single value in a variable is highly inefficient and
unnecesary. They way to store a single number is to use locals (or if
you are really worried about precision in scalars, see: )

*------------ begin example ----------------
sysuse auto, clear
corr mpg displacement
local rho = r(rho)
di `rho'
*-------------- end example ----------------
(For more on how to use examples I sent to the Statalist, see )

Hope this helps,
