array.uint64

import array

Everything here is re-exported by array, so import array is enough and the names are called as array.*. Importing array.uint64 on its own works too and reaches the same definitions.

UInt64Array: a packed array of unsigned 64-bit integers, 8 bytes per element.

UINT64_MAX and UINT64_MIN bound what an element may be; a value outside them raises rather than wrapping.

Constants

UINT64_MAX

array.UINT64_MAX: bigint

Maximum value that “should” exist in a list passed to UInt64Array.

Classes

UInt64Array

class array.UInt64Array < Array

class UInt64Array represents an array of twos-complement 64-bit unsigned integers in the platform byte order.

Values at or beyond 2^53 need Zuri’s bigint type to be represented exactly (a regular number is an IEEE-754 double, and loses precision past that point): append()/set() accept either a plain integer or a bigint (is_bigint()) for that reason.

• printable — has a @to_string(), so echo and print() show something useful
• serializable — has a @to_json(), so it can be handed straight to json.encode()
• valueable — has a @to_value(), so it converts to a plain Zuri value

UInt64Array.reverse()

array.UInt64Array.reverse() -> UInt64Array

Returns a new array containing the elements in the original array in reverse order.

Returns UInt64Array

UInt64Array.clone()

array.UInt64Array.clone() -> UInt64Array

Returns a new UInt64Array containing all items from the current array. The new array is a shallow copy of the original array.

Returns UInt64Array

UInt64Array.slice()

array.UInt64Array.slice(start, end) -> UInt64Array

Returns a new UInt64Array over [start, end) of this array (both default to the whole array; negative bounds count from the end).

Parameters

• start (?number)
• end (?number)

Returns UInt64Array
