Note that you lose a lot of precision if you just type

. mata:st_local("likethis",strofreal(st_matrix("e(b)")[1,1]))

This might be a problem if you intend to use -likethis- for further
computations. Use something like -strofreal(st_matrix("e(b)")[1,1],
"%20.0g")- to preserve precision. (Or use use a scalar instead of a
local.)
