int64

Struct · built-in type

struct int64 : IComparable<int64>, IEquatable<int64>, IHashable

A signed 64-bit integer.

Arithmetic is checked: an overflow, a division by zero or a conversion that loses the value ends the program with a panic, unless the code is unchecked (then it wraps around). See the language guide (basics).
