# int¶

Integer built-in type.

## Description¶

Signed 64-bit integer type.

It can take values in the interval `[-2^63, 2^63 - 1]`, i.e. `[-9223372036854775808, 9223372036854775807]`. 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 `: int` 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.
```

## Methods¶

 int int ( bool from ) int int ( float from ) int int ( String from )

## Method Descriptions¶

Cast a bool value to an integer value, `int(true)` will be equals to 1 and `int(false)` will be equals to 0.

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

Cast a String value to an integer value, this method is an integer parser from a string, so calling this method with an invalid integer string will return 0, a valid string will be something like `'1.7'`. This method will ignore all non-number characters, so calling `int('1e3')` will return 13.
