module Core_int

: sig

OCaml's native integer type.

The number of bits in an integer is platform dependent, being 31-bits on a 32-bit platform, and 63-bits on a 64-bit platform. int is a signed integer type. ints are also subject to overflow, meaning that Int.max_value + 1 = Int.min_value.

ints always fit in a machine word.

val of_int : int -> t

val to_int : t -> int

val of_int32 : int32 -> t option

val to_int32 : t -> int32 option

val ceil_pow2 : int -> int

ceil_pow2 x returns the smallest power of 2 that is greater than or equal to x. The implementation may only be called for x > 0. Example: ceil_pow2 17 = 32

val floor_pow2 : int -> int

floor_pow2 x returns the largest power of 2 that is less than or equal to x. The implementation may only be called for x > 0. Example: floor_pow2 17 = 16

val is_pow2 : int -> bool

is_pow2 x returns true iff x is a power of 2. is_pow2 raises if x <= 0.
