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¶
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.
