Integer built-in type.

Signed 64-bit integer type.
|
|
It can take values in the interval [code][-2^63, 2^63 - 1][/code], i.e. [code][-9223372036854775808, 9223372036854775807][/code]. Exceeding those bounds will wrap around.
|
|
[int] is a [Variant] type, and will thus be used when assigning an integer value to a [Variant]. It can also be enforced with the [code]: int[/code] type hint.
|
|

var my_variant = 0 # int, value 0.
|
|
my_variant += 4.2 # float, value 4.2.
|
|
var my_int: int = 1 # int, value 1.
|
|
my_int = 4.2 # int, value 4, the right value is implicitly cast to int.
|
|
my_int = int("6.7") # int, value 6, the String is explicitly cast with int.
|
|
var max_int = 9223372036854775807
|
|
print(max_int) # 9223372036854775807, OK.
|
|
max_int += 1
|
|
print(max_int) # -9223372036854775808, we overflowed and wrapped around.
|
|
[/gdscript]
|
|
[csharp]
|
|
int myInt = (int)"6.7".ToFloat(); // int, value 6, the String is explicitly cast with int.
|
|
// We have to use `long` here, because GDSript's `int`
|
|
// is 64 bits long while C#'s `int` is only 32 bits.
|
|
long maxInt = 9223372036854775807;
|

GD.Print(maxInt); // 9223372036854775807, OK.
|
|
maxInt++;
|
|
GD.Print(maxInt); // -9223372036854775808, we overflowed and wrapped around.
|
|
|
|
// Alternatively, if we used C#'s 32-bit `int` type, the maximum value is much smaller:
|
|
int halfInt = 2147483647;
|
|
GD.Print(halfInt); // 2147483647, OK.
|
|
halfInt++;

Cast a float value to an integer value, this method simply removes the number fractions (i.e. rounds [code]from[/code] towards zero), so for example [code]int(2.7)[/code] will be equals to 2, [code]int(0.1)[/code] will be equals to 0 and [code]int(-2.7)[/code] will be equals to -2. This operation is also called truncation.
