Module Stdlib_upstream_compatible.Int64_uSource
Unboxed 64-bit integers. This file primarily duplicates functionality from the Int64 module, but for int64#.
This module provides operations on the type int64# of unboxed signed 64-bit integers. Unlike the built-in int type, the type int64# is guaranteed to be exactly 64-bit wide on all platforms. All arithmetic operations over int64# are wrapping, not truncating.
An alias for the type of unboxed 64-bit integers.
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 unboxed 64-bit integers.
Integer remainder. If y is not zero, the result of Int64_u.rem x y satisfies the following property: x = Int64_u.add (Int64_u.mul (Int64_u.div x y) y) (Int64_u.rem x y). If y = 0, Int64_u.rem x y raises Division_by_zero.
Same as rem, except that arguments and result are interpreted as unsigned unboxed 64-bit integers.
Int64_u.shift_left x y shifts x to the left by y bits. The result is unspecified if y < 0 or y >= 64.
Int64_u.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 >= 64.
Int64_u.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 >= 64.
Convert the given integer (type int) to an unboxed 64-bit integer (type int64#).
Convert the given unboxed 64-bit integer (type int64#) to an integer (type int). On 64-bit platforms, the 64-bit integer is taken modulo 263, i.e. the high-order bit is lost during the conversion. On 32-bit platforms, the 64-bit integer is taken modulo 231, i.e. the top 33 bits are lost during the conversion.
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 an unboxed 64-bit integer, discarding the fractional part (truncate towards 0). If the truncated floating-point number is outside the range [Int64_u.min_int, Int64_u.max_int], no exception is raised, and an unspecified, platform-dependent integer is returned.
Convert the given unboxed 64-bit integer to a floating-point number.
Convert the given 32-bit integer (type int32) to an unboxed 64-bit integer (type int64).
Convert the given unboxed 64-bit integer (type int64) to a 32-bit integer (type int32). The 64-bit integer is taken modulo 232, i.e. the top 32 bits are lost during the conversion.
Convert the given native integer (type nativeint) to an unboxed 64-bit integer (type int64#).
Convert the given unboxed 64-bit integer (type int64#) to a native integer. On 32-bit platforms, the 64-bit integer is taken modulo 232. On 64-bit platforms, the conversion is exact.
Convert the given unboxed 32-bit integer (type int32) to an unboxed 64-bit integer (type int64).
Convert the given unboxed 64-bit integer (type int64) to an unboxed 32-bit integer (type int32). The 64-bit integer is taken modulo 232, i.e. the top 32 bits are lost during the conversion.
Convert the given unboxed native integer (type nativeint) to an unboxed 64-bit integer (type int64#).
Convert the given unboxed 64-bit integer (type int64#) to an unboxed native integer. On 32-bit platforms, the 64-bit integer is taken modulo 232. On 64-bit platforms, the conversion is exact.
Convert the given string to an unboxed 64-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*Int64_u.max_int+1]. If the input exceeds Int64_u.max_int it is converted to the signed integer Int64.min_int + input - Int64_u.max_int - 1.
The _ (underscore) character can appear anywhere in the string and is ignored.
Return the string representation of its argument, in decimal.
Return the internal representation of the given float according to the IEEE 754 floating-point 'double format' bit layout. Bit 63 of the result represents the sign of the float; bits 62 to 52 represent the (biased) exponent; bits 51 to 0 represent the mantissa.
Return the floating-point number whose internal representation, according to the IEEE 754 floating-point 'double format' bit layout, is the given int64#.
The comparison function for unboxed 64-bit integers, with the same specification as Stdlib.compare.
Same as compare, except that arguments are interpreted as unsigned unboxed 64-bit integers.
