int
A built-in type for integers.
Description
Signed 64-bit integer type. This means that it can take values from -2^63 to 2^63 - 1, i.e. from -9223372036854775808 to 9223372036854775807. 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.
\ Note: In a boolean context, an int will evaluate to false if it equals 0, and to true 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
int x = 1; // x is 1
x = (int)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
You can use the 0b literal for binary representation, the 0x literal for hexadecimal representation, and the _ symbol to separate long numbers and improve readability.
var x = 0b1001 # x is 9
var y = 0xF5 # y is 245
var z = 10_000_000 # z is 10000000
int x = 0b1001; // x is 9
int y = 0xF5; // y is 245
int z = 10_000_000; // z is 10000000

Operators
Constructor Descriptions
Constructs an int set to 0.
Constructs an int as a copy of the given int.
Constructs a new int from a String, following the same rules as String.to_int().
Constructs a new int from a bool. true is converted to 1 and false is converted to 0.
Constructs a new int from a float. This will truncate the float, discarding anything after the floating point.
Operator Descriptions
bool operator !=\ (\ right: float\ ) 🔗
Returns true if the int is not equivalent to the float.
bool operator !=\ (\ right: int\ ) 🔗
Returns true if the int\ s are not equal.
int operator %\ (\ right: int\ ) 🔗
Returns the remainder after dividing two int\ s. Uses truncated division, which returns a negative number if the dividend is negative. If this is not desired, consider using @GlobalScope.posmod().
print(6 % 2) # Prints 0
print(11 % 4) # Prints 3
print(-5 % 3) # Prints -2
int operator &\ (\ right: int\ ) 🔗
Performs the bitwise AND operation.
print(0b1100 & 0b1010) # Prints 8 (binary 1000)
This is useful for retrieving binary flags from a variable.
var flags = 0b101
# Check if the first or second bit are enabled.
if flags & 0b011:
do_stuff() # This line will run.
Color **operator ***\ (\ right: Color\ ) 🔗
Multiplies each component of the Color by the int.
Quaternion **operator ***\ (\ right: Quaternion\ ) 🔗
Multiplies each component of the Quaternion by the int. This operation is not meaningful on its own, but it can be used as a part of a larger expression.
Vector2 **operator ***\ (\ right: Vector2\ ) 🔗
Multiplies each component of the Vector2 by the int.
print(2 * Vector2(1, 4)) # Prints (2, 8)
Vector2i **operator ***\ (\ right: Vector2i\ ) 🔗
Multiplies each component of the Vector2i by the int.
Vector3 **operator ***\ (\ right: Vector3\ ) 🔗
Multiplies each component of the Vector3 by the int.
Vector3i **operator ***\ (\ right: Vector3i\ ) 🔗
Multiplies each component of the Vector3i by the int.
Vector4 **operator ***\ (\ right: Vector4\ ) 🔗
Multiplies each component of the Vector4 by the int.
Vector4i **operator ***\ (\ right: Vector4i\ ) 🔗
Multiplies each component of the Vector4i by the int.
float **operator ***\ (\ right: float\ ) 🔗
Multiplies the float by the int. The result is a float.
int **operator ***\ (\ right: int\ ) 🔗
Multiplies the two int\ s.
float **operator ****\ (\ right: float\ ) 🔗
Raises an int to a power of a float. The result is a float.
print(2 ** 0.5) # Prints 1.4142135623731
int **operator ****\ (\ right: int\ ) 🔗
Raises the left int to a power of the right int.
print(3 ** 4) # Prints 81
float operator +\ (\ right: float\ ) 🔗
Adds the int and the float. The result is a float.
int operator +\ (\ right: int\ ) 🔗
Adds the two int\ s.
float operator -\ (\ right: float\ ) 🔗
Subtracts the float from the int. The result is a float.
int operator -\ (\ right: int\ ) 🔗
Subtracts the two int\ s.
float operator /\ (\ right: float\ ) 🔗
Divides the int by the float. The result is a float.
print(10 / 3.0) # Prints 3.33333333333333
int operator /\ (\ right: int\ ) 🔗
Divides the two int\ s. The result is an int. This will truncate the float, discarding anything after the floating point.

print(0b1010 >> 2) # Prints 2 (binary 10)
int operator ^\ (\ right: int\ ) 🔗
Performs the bitwise XOR operation.
print(0b1100 ^ 0b1010) # Prints 6 (binary 110)
Returns the same value as if the + was not there. Unary + does nothing, but sometimes it can make your code more readable.
Returns the negated value of the int. If positive, turns the number negative. If negative, turns the number positive. If zero, does nothing.
int operator |\ (\ right: int\ ) 🔗
Performs the bitwise OR operation.
print(0b1100 | 0b1010) # Prints 14 (binary 1110)
This is useful for storing binary flags in a variable.
var flags = 0

Performs the bitwise NOT operation on the int. Due to 2's complement, it's effectively equal to -(int + 1).
print(~4) # Prints -5
print(~(-7)) # Prints 6
