Cbn (coq-core.Cbn)

val whd_cbn : 
  CClosure.RedFlags.reds ->
  Environ.env ->
  Evd.evar_map ->
  EConstr.constr ->
  EConstr.constr

Weak-head cbn reduction. Despite the name, the cbn reduction is a complex reduction distinct from call-by-name or call-by-need.

val norm_cbn : 
  CClosure.RedFlags.reds ->
  Environ.env ->
  Evd.evar_map ->
  EConstr.constr ->
  EConstr.constr

Strong variant of cbn reduction.
