Module `Tezos_raw_protocol_011_PtHangz2.Tez_repr`Source

type t

Internal representation of the Tez currency. Behaves mostly like a natural number where number 1 represents 1/1,000,000 Tez (1 micro-Tez or mutez). It's protected from ever becoming negative and overflowing by special arithmetic functions, which fail in case something undesired would happen. When divided, it's always rounded down to 1 mutez.

Internally encoded as int64, which may be relevant to guard against overflow errors.

val (-?) : 
  t ->
  t ->
  t Tezos_protocol_environment_011_PtHangz2.Error_monad.tzresult

Tez subtraction.

a -? b is the difference between a and b given that b is greater or equal to a. Otherwise an error (Subtraction underflow) is returned.

Source

val (+?) : 
  t ->
  t ->
  t Tezos_protocol_environment_011_PtHangz2.Error_monad.tzresult

Tez addition.

a +? b is the sum of a and b or an Addition overflow error in case of overflow.

Source

val (*?) : 
  t ->
  int64 ->
  t Tezos_protocol_environment_011_PtHangz2.Error_monad.tzresult

Tez multiplication by an integral factor.

a *? m is a multiplied by m (which must be non-negative) or a Multiplication_overflow error.

Source

val (/?) : 
  t ->
  int64 ->
  t Tezos_protocol_environment_011_PtHangz2.Error_monad.tzresult

Tez division by an integral divisor.

a /? d is a divided by d (which must be positive). Given that d is positive, this function is safe. The result is rounded down to 1 mutez.

Sourceval to_mutez : t -> int64

Sourceval of_mutez : int64 -> t option

of_mutez n (micro tez) is None if n is negative

Sourceval of_mutez_exn : int64 -> t

of_mutez_exn n fails if n is negative. It should only be used at toplevel for constants.

Sourceval mul_exn : t -> int -> t

It should only be used at toplevel for constants.
