Name
Shl -- shift bits to the left (V1.5)
Synopsis
result = Shl(a, x[, bignum])
Function
This function shifts a by x bits to the left, padding the holes with zero bits. This is called a logical shift. a is converted to an unsigned 32-bit integer variable before the shift (unless bignum is set to True).

Starting with Hollywood 9.0, there is an optional bignum argument. If this is set to True, Shl() will be able to operate on integers larger than 2^31 but keep in mind that Shl() still won't be possible to use the full 64-bit integer range because Hollywood's numeric type is a 64-bit floating point number and is thus limited to integers in the range of [-9007199254740992,9007199254740992].

Inputs
a
source value
x
number of bits to shift
bignum
optional: whether or not to use 64-bit integers (defaults to False) (V9.0)
Results
result
integer result
Example
a = Shl(256, 3)
This returns 2048.
