Module Stdlib.Int32

The 32-bit integer 0.

The 32-bit integer 1.

The 32-bit integer -1.

Unary negation.

Addition.

Subtraction.

Multiplication.

Integer division. This division rounds the real quotient of its arguments towards zero, as specified for (/).

Same as Int32.div, except that arguments and result are interpreted as unsigned 32-bit integers.

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.

Same as Int32.rem, except that arguments and result are interpreted as unsigned 32-bit integers.

Successor. Int32.succ x is Int32.add x Int32.one.

Predecessor. Int32.pred x is Int32.sub x Int32.one.

abs x is the absolute value of x. On min_int this is min_int itself and thus remains negative.

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 Int32.to_int, but interprets the argument as an unsigned integer. Returns None if the unsigned value of the argument cannot fit into an int.

Convert the given floating-point number to a 32-bit integer, discarding the fractional part (truncate towards 0). If the truncated floating-point number is outside the range [Int32.min_int, Int32.max_int], no exception is raised, and an unspecified, platform-dependent integer is returned.

Convert the given 32-bit integer to a floating-point number.

Convert the given string to a 32-bit integer. The string is read in decimal (by default, or if the string begins with 0u) or in hexadecimal, octal or binary if the string begins with 0x, 0o or 0b respectively.

The 0u prefix reads the input as an unsigned integer in the range [0, 2*Int32.max_int+1]. If the input exceeds Int32.max_int it is converted to the signed integer Int32.min_int + input - Int32.max_int - 1.

The _ (underscore) character can appear anywhere in the string and is ignored.

Same as of_string, but return None instead of raising.

Return the string representation of its argument, in signed decimal.

Return the internal representation of the given float according to the IEEE 754 floating-point 'single format' bit layout. Bit 31 of the result represents the sign of the float; bits 30 to 23 represent the (biased) exponent; bits 22 to 0 represent the mantissa.

Return the floating-point number whose internal representation, according to the IEEE 754 floating-point 'single format' bit layout, is the given int32.

An alias for the type of 32-bit integers.

The comparison function for 32-bit integers, with the same specification as 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.

Same as Int32.compare, except that arguments are interpreted as unsigned 32-bit integers.

The equal function for int32s.

Return the smaller of the two arguments.

Return the greater of the two arguments.
