  Measurements of the differential production of electrons from
open-heavy-flavor hadrons with charm- and bottom-quark content in $p$$+$$p$
collisions at $\sqrt{s}=200$ GeV are presented. The measurements proceed
through displaced-vertex analyses of electron tracks from the semileptonic
decay of charm and bottom hadrons using the PHENIX silicon-vertex detector. The
relative contribution of electrons from bottom decays to inclusive
heavy-flavor-electron production is found to be consistent with
fixed-order-plus-next-to-leading-log perturbative-QCD calculations within
experimental and theoretical uncertainties. These new measurements in $p$$+$$p$
collisions provide a precision baseline for comparable forthcoming measurements
in A$+$A collisions.
