Core functions
val tag : unit -> int

start global tagging counter

val primal : t -> t

get primal component of DF or DR type

val primal' : t -> t

iteratively get primal component of DF or DR type until the component itself is not DF/DR

val zero : t -> t

return a zero value, which type decided by the input value

val reset_zero : t -> t

reset_zero x iteratively resets all elements included in x

val tangent : t -> t

get the tangent component of input, if the data type is suitable

val adjref : t -> t Stdlib.ref

get the adjref component of input, if the data type is suitable

val adjval : t -> t

get the adjval component of input, if the data type is suitableTODO

val shape : t -> int array

get the shape of primal' value of input

val is_float : t -> bool
