<brief_description>
|
|
A built-in type for integers.
|
|
</brief_description>

<description>

|
Signed 64-bit integer type. This means that it can take values from [code]-2^63[/code] to [code]2^63 - 1[/code], i.e. from [code]-9223372036854775808[/code] to [code]9223372036854775807[/code]. When it exceeds these bounds, it will wrap around.
|
|
[int]s can be automatically converted to [float]s when necessary, for example when passing them as arguments in functions. The [float] will be as close to the original integer as possible.
|
|
Likewise, [float]s can be automatically converted into [int]s. This will truncate the [float], discarding anything after the floating point.
|
|
[b]Note:[/b] In a boolean context, an [int] will evaluate to [code]false[/code] if it equals [code]0[/code], and to [code]true[/code] otherwise.

var x: int = 1 # x is 1
|

x = 4.2 # x is 4, because 4.2 gets truncated
|

var max_int = 9223372036854775807 # Biggest value an int can store
|
|
max_int += 1 # max_int is -9223372036854775808, because it wrapped around
|

[csharp]
|
|
int x = 1; // x is 1
|
|
x = 4.2; // x is 4, because 4.2 gets truncated
|
|
// We use long below, because GDScript's int is 64-bit while C#'s int is 32-bit.
|
|
long maxLong = 9223372036854775807; // Biggest value a long can store
|
|
maxLong++; // maxLong is now -9223372036854775808, because it wrapped around.
|
|
|
|
// Alternatively with C#'s 32-bit int type, which has a smaller maximum value.
|
|
int maxInt = 2147483647; // Biggest value an int can store
|
|
maxInt++; // maxInt is now -2147483648, because it wrapped around

In GDScript, you can use the [code]0b[/code] literal for binary representation, the [code]0x[/code] literal for hexadecimal representation, and the [code]_[/code] symbol to separate long numbers and improve readability.
