Module Make.Int32Source
32-bit integers.
This module provides operations on the type int32 of signed 32-bit integers. Unlike the built-in int type, the type int32 is guaranteed to be exactly 32-bit wide on all platforms. All arithmetic operations over int32 are taken modulo 232.
Performance notice: values of type int32 occupy more memory space than values of type int, and arithmetic operations on int32 are generally slower than those on int. Use int32 only when the application requires exact 32-bit arithmetic.
Literals for 32-bit integers are suffixed by l:
let zero: int32 = 0l
let one: int32 = 1l
let m_one: int32 = -1lThe 32-bit integer 0.
The 32-bit integer 1.
The 32-bit integer -1.
Unary negation.
Addition.
Subtraction.
Multiplication.
Integer division. Raise Division_by_zero if the second argument is zero. This division rounds the real quotient of its arguments towards zero, as specified for Stdlib.(/).
Integer remainder. If y is not zero, the result of Int32.rem x y satisfies the following property: x = Int32.add (Int32.mul (Int32.div x y) y) (Int32.rem x y). If y = 0, Int32.rem x y raises Division_by_zero.
Successor. Int32.succ x is Int32.add x Int32.one.
Predecessor. Int32.pred x is Int32.sub x Int32.one.
Return the absolute value of its argument.
The greatest representable 32-bit integer, 231 - 1.
The smallest representable 32-bit integer, -231.
Bitwise logical and.
Bitwise logical or.
Bitwise logical exclusive or.
Bitwise logical negation.
Int32.shift_left x y shifts x to the left by y bits. The result is unspecified if y < 0 or y >= 32.
Int32.shift_right x y shifts x to the right by y bits. This is an arithmetic shift: the sign bit of x is replicated and inserted in the vacated bits. The result is unspecified if y < 0 or y >= 32.
Int32.shift_right_logical x y shifts x to the right by y bits. This is a logical shift: zeroes are inserted in the vacated bits regardless of the sign of x. The result is unspecified if y < 0 or y >= 32.
Convert the given integer (type int) to a 32-bit integer (type int32). On 64-bit platforms, the argument is taken modulo 232.
Convert the given 32-bit integer (type int32) to an integer (type int). On 32-bit platforms, the 32-bit integer is taken modulo 231, i.e. the high-order bit is lost during the conversion. On 64-bit platforms, the conversion is exact.
Same as of_string, but return None instead of raising.
Return the string representation of its argument, in signed decimal.
An alias for the type of 32-bit integers.
The comparison function for 32-bit integers, with the same specification as Stdlib.compare. Along with the type t, this function compare allows the module Int32 to be passed as argument to the functors Set.Make and Map.Make.
