type t = uint128

The specific integer type

val zero : t

val (+) : t -> t -> t

Addition

val (-) : t -> t -> t

Subtraction

val (*) : t -> t -> t

Multiplication

val (/) : t -> t -> t

Integer division. Raise Division_by_zero if the second argument is zero. This division rounds the real quotient of its arguments towards zero, as specified for (/).

val add : t -> t -> t

Addition

val sub : t -> t -> t

Subtraction

val mul : t -> t -> t

Multiplication

val div : t -> t -> t

Integer division. Raise Division_by_zero if the second argument is zero. This division rounds the real quotient of its arguments towards zero, as specified for (/).

val rem : t -> t -> t

Integer remainder. If y is not zero, the result of rem x y satisfies the following property: x = add (mul (div x y) y) (rem x y). If y = 0, rem x y raises Division_by_zero.

val shift_left : t -> int -> t

shift_left x y shifts x to the left by y bits. The result is unspecified if y < 0 or y >= bits.

val shift_right : t -> int -> t

shift_right x y shifts x to the right by y bits. If this is a signed integer, this is an arithmetic shift: the sign bit of x is replicated and inserted in the vacated bits. The result is unspecified if y < 0 or y >= bits. For an unsigned integer, this is identical to shift_right_logical.

val shift_right_logical : t -> int -> t

shift_right_logical x y shifts x to the right by y bits. This is a logical shift: zeroes are inserted in the vacated bits regardless if x is a signed or unsiged integer. The result is unspecified if y < 0 or y >= bits.

val of_bytes_big_endian : Bytes.t -> int -> t

of_bytes_big_endian buffer offset creates an integer value of type t from the buffer buffer starting at offset offset. The byte order is interpreted to be big endian. If the buffer does not hold enough bytes for this integer, i.e. if (Bytes.length buffer) < (offset + (bits / 8)), the function will raise Invalid_argument "index out of bounds".

val of_bytes_little_endian : Bytes.t -> int -> t

of_bytes_big_endian buffer offset creates an integer value of type t from the buffer buffer starting at offset offset. The byte order is interpreted to be little endian. If the buffer does not hold enough bytes for this integer, i.e. if (Bytes.length buffer) < (offset + (bits / 8)), the function will raise Invalid_argument "index out of bounds".

val to_bytes_big_endian : t -> Bytes.t -> int -> unit

to_bytes_big_endian i buffer offset writes the integer i to the buffer buffer starting at offset offset. The byte order used is big endian. If the buffer does not hold enough bytes, i.e. if (Bytes.length buffer) < (offset + (bits / 8)), the function will raise Invalid_argument "index out of bounds".

val to_bytes_little_endian : t -> Bytes.t -> int -> unit

to_bytes_little_endian i buffer offset writes the integer i to the buffer buffer starting at offset offset. The byte order used is little endian. If the buffer does not hold enough bytes, i.e. if (Bytes.length buffer) < (offset + (bits / 8)), the function will raise Invalid_argument "index out of bounds".
