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.

rem x y is the remainder x mod y. See Stdlib.(mod) 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.

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

An unseeded hash function for ints, with the same output value as Hashtbl.hash. This function allows this module to be passed as argument to the functor Hashtbl.Make.
