ShiftLeft()

Does a left arithmetic shift of the bits in an integer.

int = ShiftLeft(integer int1, integer shift)

Argument	Contents
int1	An integer
shift	Number of bits to shift left, from 1 to 32; a negative value will shift right

An integer with an arithmetic shift of the bits the specified number of places to the left.

Bits are dropped from the left end, and new bits on the right are set to 0.
The sign bit can change if a different value moves into the sign (leftmost) bit.
Until the sign bit is changed, ShiftLeft() is the equivalent of multiplying by powers of 2.

int = ShiftLeft(15, 1) // int = 30: in binary, 1111 becomes 11110

int = ShiftLeft(1073741824, 1) // int = -2147483648: leftmost numeric bit moved to sign bit

Function	Summary
BitwiseAnd()	Computes the bitwise AND of two integers
BitwiseNot()	Computes the bitwise NOT of an integer
BitwiseOr()	Computes the bitwise OR of two integers
BitwiseXor()	Computes the bitwise exclusive OR of an integer
ShiftRight()	Does a right arithmetic shift of the bits in an integer
