Integer division. This division rounds the real quotient of its arguments towards zero, as specified for Stdlib.(/)
.
Same as 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 rem
, except that arguments and result are interpreted as unsigned 32-bit integers.
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 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). The result of the conversion is undefined if, after truncation, the number is outside the range [Int32.min_int
, Int32.max_int
].
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.
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
.
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
.
Same as compare
, except that arguments are interpreted as unsigned 32-bit integers.
