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. ints can be automatically converted to floats when necessary, for example when passing them as arguments in functions. The float will be as close to the original integer as possible. Likewise, floats can be automatically converted into ints. 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

Constructors

int int()

Constructs an int set to 0.

int int(int from)

Constructs an int as a copy of the given int.

int int(bool from)

Constructs a new int from a bool. true is converted to 1 and false is converted to 0.

int int(float from)

Constructs a new int from a float. This will truncate the float, discarding anything after the floating point.

Operators

bool operator !=(int right)

Returns true if the ints are not equal.

int operator %(int right)

Returns the remainder after dividing two ints. 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 &(int right)

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.

Quaternion operator *(Quaternion right)

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 *(Vector2 right)

Multiplies each component of the Vector2 by the int.

				print(2 * Vector2(1, 4)) # Prints (2, 8)

int operator *(int right)

Multiplies the two ints.

float operator **(float right)

Raises an int to a power of a float. The result is a float.

				print(2 ** 0.5) # Prints 1.4142135623731

int operator **(int right)

Raises the left int to a power of the right int.

				print(3 ** 4) # Prints 81

int operator -(int right)

Subtracts the two ints.

float operator /(float right)

Divides the int by the float. The result is a float.

				print(10 / 3.0) # Prints 3.33333333333333

int operator /(int right)

Divides the two ints. The result is an int. This will truncate the float, discarding anything after the floating point.

				print(6 / 2) # Prints 3
				print(5 / 3) # Prints 1

bool operator <(int right)

Returns true if the left int is less than the right int.

int operator <<(int right)

Performs the bitwise shift left operation. Effectively the same as multiplying by a power of 2.

				print(0b1010 << 1) # Prints 20 (binary 10100)
				print(0b1010 << 3) # Prints 80 (binary 1010000)

bool operator <=(float right)

Returns true if the int is less than or equal to the float.

bool operator <=(int right)

Returns true if the left int is less than or equal to the right int.

bool operator ==(int right)

Returns true if the two ints are equal.

bool operator >(int right)

Returns true if the left int is greater than the right int.

bool operator >=(float right)

Returns true if the int is greater than or equal to the float.

bool operator >=(int right)

Returns true if the left int is greater than or equal to the right int.

int operator >>(int right)

Performs the bitwise shift right operation. Effectively the same as dividing by a power of 2.

				print(0b1010 >> 1) # Prints 5 (binary 101)
				print(0b1010 >> 2) # Prints 2 (binary 10)

int operator ^(int right)

Performs the bitwise XOR operation.

				print(0b1100 ^ 0b1010) # Prints 6 (binary 110)

int operator unary+()

Returns the same value as if the + was not there. Unary + does nothing, but sometimes it can make your code more readable.

int operator unary-()

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 |(int right)

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
				flags |= 0b101 # Turn the first and third bits on.

int operator ~()

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
