Module Checked_ointSource

checked_oint is an OCaml library for checked integer arithmetic.

This library supports signed and unsigned integers of bitnesses 8, 16, 32, 64, and 128. S is the main signature that contains common operations for all integer types; specific implementations are named U8, U16, and so on.

Sourceexception Out_of_range

The exception raised on underflows/overflows.

Sourcetype u8

An unsigned 8-bit integer.

Sourceval compare_u8 : u8 -> u8 -> Ppx_deriving_runtime.int
Sourcetype u16

An unsigned 16-bit integer.

Sourceval compare_u16 : u16 -> u16 -> Ppx_deriving_runtime.int
Sourcetype u32

An unsigned 32-bit integer.

Sourceval compare_u32 : u32 -> u32 -> Ppx_deriving_runtime.int
Sourcetype u64

An unsigned 64-bit integer.

Sourceval compare_u64 : u64 -> u64 -> Ppx_deriving_runtime.int
Sourcetype u128

An unsigned 128-bit integer.

Sourceval compare_u128 : u128 -> u128 -> Ppx_deriving_runtime.int
Sourcetype i8

A signed 8-bit integer.

Sourceval compare_i8 : i8 -> i8 -> Ppx_deriving_runtime.int
Sourcetype i16

A signed 16-bit integer.

Sourceval compare_i16 : i16 -> i16 -> Ppx_deriving_runtime.int
Sourcetype i32

A signed 32-bit integer.

Sourceval compare_i32 : i32 -> i32 -> Ppx_deriving_runtime.int
Sourcetype i64

A signed 64-bit integer.

Sourceval compare_i64 : i64 -> i64 -> Ppx_deriving_runtime.int
Sourcetype i128

A signed 128-bit integer.

Sourceval compare_i128 : i128 -> i128 -> Ppx_deriving_runtime.int
Sourcetype generic =
  1. | U8 of u8
  2. | U16 of u16
  3. | U32 of u32
