The type for integer values.

zero is the integer 0.

one is the integer 1.

minus_one is the integer -1.

neg x is ~-x.

add x y is the addition x + y.

sub x y is the subtraction x - y.

mul x y is the multiplication x * y.

div x y is the division x / y. See Stdlib.(/) for details.

succ x is add x 1.

pred x is sub x 1.

abs x is the absolute value of x. That is x if x is positive and neg x if x is negative. Warning. This may be negative if the argument is min_int.

max_int is the greatest representable integer, 2Sys.int_size - 1-1.

min_int is the smallest representable integer, -2Sys.int_size - 1.

logand x y is the bitwise logical and of x and y.

logor x y is the bitwise logical or of x and y.

logxor x y is the bitwise logical exclusive or of x and y.

lognot x is the bitwise logical negation of x.

shift_left x n shifts x to the left by n bits. The result is unspecified if n < 0 or n > Sys.int_size.

shift_right x n shifts x to the right by n bits. This is an arithmetic shift: the sign bit of x is replicated and inserted in the vacated bits. The result is unspecified if n < 0 or n > Sys.int_size.

shift_right x n shifts x to the right by n bits. This is a logical shift: zeroes are inserted in the vacated bits regardless of the sign of x. The result is unspecified if n < 0 or n > Sys.int_size.

equal x y is true if and only if x = y.

compare x y is Stdlib.compare x y but more efficient.

Return the smaller of the two arguments.

• since 4.13

Return the greater of the two arguments.

• since 4.13

to_float x is x as a floating point number.

of_float x truncates x to an integer. The result is unspecified if the argument is nan or falls outside the range of representable integers.

to_string x is the written representation of x in decimal.

A seeded hash function for ints, with the same output value as Hashtbl.seeded_hash. This function allows this module to be passed as argument to the functor Hashtbl.MakeSeeded.

• since 5.1

hash x computes the hash of x.

sign x return 0 if x = 0, -1 if x < 0 and 1 if x > 0. Same as compare x 0.

pow base exponent returns base raised to the power of exponent. pow x y = x^y for positive integers x and y. Raises Invalid_argument if x = y = 0 or y < 0.

• since 0.11

floor_div x n is integer division rounding towards negative infinity. It satisfies x = m * floor_div x n + rem x n.

• since 1.2

rem x n is the remainder of dividing x by n, with the same sign as n.

• since 1.2

pp ppf x prints the integer x on ppf.

of_string s converts the given string s into an integer. Safe version of of_string_exn.

• since 0.13

of_string_exn s converts the given string s to an integer. Alias to int_of_string.

• raises Failure

  in case of failure.

• since 3.0

pp_binary ppf x prints x on ppf. Print as "0b00101010".

• since 0.20

to_string_binary x returns the string representation of the integer x, in binary.

• since 0.20

range_by ~step i j iterates on integers from i to j included, where the difference between successive elements is step. Use a negative step for a decreasing list.

• raises Invalid_argument

  if step=0.

• since 1.2

range i j iterates on integers from i to j included . It works both for decreasing and increasing ranges.

• since 1.2

range' i j is like range but the second bound j is excluded. For instance range' 0 5 = Iter.of_list [0;1;2;3;4].

• since 1.2

Number of bits set to 1

• since 3.0
