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. int
s
are also subject to overflow, meaning that Int.max_value + 1 = Int.min_value
.
int
s always fit in a machine word.

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
.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
.val is_pow2 : int -> bool
is_pow2 x
returns true iff x
is a power of 2. is_pow2
raises if x <= 0
