///
/// The number can be negative, zero, or positive. As Typst uses 64 bits to
/// store integers, integers cannot be smaller than `{-9223372036854775808}` or
/// larger than `{9223372036854775807}`.
/// larger than `{9223372036854775807}`. Integer literals are always positive,
/// so a negative integer such as `{-1}` is semantically the negation `-` of the
/// positive literal `1`. A positive integer greater than the maximum value and
/// a negative integer less than or equal to the minimum value cannot be
/// represented as an integer literal, and are instead parsed as a `{float}`.
/// The minimum integer value can still be obtained through integer arithmetic.
///
/// The number can also be specified as hexadecimal, octal, or binary by
/// starting it with a zero followed by either `x`, `o`, or `b`.
